Introduction to Perl index

The index is the function available in Perl to get the index. If we want to know the index or the position of the substring, then we can use this function to get the value. By the use of the index function, we can also get the position of the character in the string. In the short index, the function is used to get the position or index where the substring or character is placed in the given string; inside index methods, we just have to pass our parameters. In the coming section, we will discuss this method more in detail to better understand the method to use.

Syntax

We can directly use this function in the program without including any library because it is an inbuild function available in Perl to deal with String. Let’s see its syntax for better understating how to use it in programming see below;

1. index(text, substring, index): calculating with index.

In the above syntax, we are passing three parameters as the input. The last parameter is not mandatory to pass.

2. index(text, substring): without index being passed.

In the above syntax, we pass two parameters as input to calculate and return us the value.

index("String to find from", "string to search"); index("some string", "some",0)

Above, you can see the sample syntax for the index method to use in Perl programming.

How does index work in Perl?

As of now, we know that index is used to get the position of the element in the string. This method can take two or three parameters. We have some scenarios where we want to know the actual position of the character or any substring into the string so we can call this method and get the position. By the use of this method, we can even specify the index of the substring from which we want them to evaluate the position. In this section, we will first discuss the method signature of the index and return type. Let’s see the signature of the method in detail see below;

1. index(text, substring, index): This method takes three parameters as the input. By using this method, we can get the actual position of the character or substring inside a string message. Let’s discuss its signature in detail;

text: This parameter is used to pass our actual string from which we want to calculate our character or substring position value. We can create a normal string in Perl and pass this inside the method.

substring: This parameter is the original substring that we want the index() method to calculate its value and return the position for that element in a given string.

index: This is the optional parameter in this method. If you want to set the starting index for the substring, then mention this parameter while calling the index() method in Perl. If we do not mention it, it just takes up the default value of ‘0’.

2. index(text, substring): This method is also used to get the index of the substring. But it has one difference from the above one is that here we are not mentioning the index or the starting index for a substring so that it will take up as default of ‘0’.

Apart from all this, all the things are similar in both the methods available in Perl. These are the in-build method of Perl, so we do not need to mention or import any library in our project before using it. Let’s see one sample example for beginners how to use this in programming see below;

Example:

# Your code here! $mystr = "Hello to find !!";. $myresult = index ($mystr, 'find');

In the above lines of code, we are trying to find a substring into the string. First, we have created one string object and assign it some value. After this, we call the ‘index’ method and pass our string inside it with the value to be searched as ‘find’ in the string. So it returns us an integer value with its actual position in the string.

Examples

Different examples are mentioned below:

Example #1

In this example, we are using the index method without index param to get the substring position in Perl.

Code:

# Your code here! $mystr1 = "I am first string "; $mystr2 = "I am second string "; $mystr3 = "I am third string "; $mystr4 = "I am fourth string "; $mystr5 = "I am fifth string "; $myresult1 = index ($mystr1, 'first'); $myresult2 = index ($mystr2, 'second'); $myresult3 = index ($mystr3, 'third'); $myresult4 = index ($mystr4, 'fourth'); $myresult5 = index ($mystr5, 'fifth'); print "Result for each string are :::n"; print "One: $myresult1n"; print "two: $myresult2n"; print "three: $myresult3n"; print "four: $myresult4n"; print "five: $myresult5n";

Example #2

In this example, we are using the index method with index param to get the substring position in Perl.

Code:

# Your code here! $mystr1 = "I am first string "; $mystr2 = "I am second string "; $mystr3 = "I am third string "; $mystr4 = "I am fourth string "; $mystr5 = "I am fifth string "; $myresult1 = index ($mystr1, 'first', 3); $myresult2 = index ($mystr2, 'second', 2); $myresult3 = index ($mystr3, 'third', 1); $myresult4 = index ($mystr4, 'fourth'. 1); $myresult5 = index ($mystr5, 'fifth', 0); print "Result for each string are :::n"; print "One: $myresult1n"; print "two: $myresult2n"; print "three: $myresult3n"; print "four: $myresult4n"; print "five: $myresult5n";

Output:

Conclusion

We may have some scenarios where we need to have the actual position of the substring from the string so we can use the index() method in Perl. We can also evaluate the position of the character by using the same method in Perl. Also, this can help me know whether the character or substring is present in the string or not.

How Or Operator Works In Perl With Examples?

Introduction to Perl OR

Perl OR operator which is also termed as the logical operator is assigned to be true only if the two operands are non-zero values.

C-style Logical OR administrator duplicates a piece in the event that it exists in one or the other operand.

A Perl administrator is a progression of at least one images utilized as a feature of the grammar of a language. Henceforth, a few people consider Perl an “administrator arranged language”.

Every administrator works on at least zero operands.

Consider an administrator an exceptional kind of capacity the parser comprehends and its operands as contentions.

Web development, programming languages, Software testing & others

$s OR $p = 1(true)

Where,

OR is the logical operator used in binary value calculation of the two variables $s and $p.

How OR operator works in Perl?

Now we see examples on how the logical OR operator works in Perl.

Example #1

Code:

$s = false; $p = true; $v = ($s or $p); print "Result of $s or $p = $vn"; $s = 0; $v= not($s); print "Result of not($s)= $vn";

Output:

In the above program, we first assign values to s and p variables and then use the logical OR operator to determine the true and false values and the Perl program is executed and the output is as shown in the above snapshot.

Example #2 $s = true; $p = true; $v = ($s or $p); print "Result of $s or $p = $vn"; $s = 0; $v= not($s); print "Result of not($s)= $vn";

Output:

In the above program, we assign both s and p variables as true and use the logical OR operator to find out the result. Thus the program is executed and the output is as shown in the above snapshot.

perldoc perlop and perldoc perlsyn give voluminous data about Perl’s administrators, however, the docs accept that you’re as of now acquainted with a couple of basic software engineering ideas. Luckily, you’ll perceive these thoughts from composed language and rudimentary arithmetic, regardless of whether you’ve never heard their convoluted names.

The priority of an administrator oversees when Perl ought to assess it in an articulation. Perl assesses the administrator with the most elevated priority first, at that point the following most elevated, right to the least priority. Recall fundamental math? Increase and gap before you add and deduct. That is priority.

The associativity of an administrator oversees whether it assesses from left to right or option to left. Option is left affiliated, with the end goal that 2 + 3 + 4 assesses 2 + 3 first, at that point adds 4 to the outcome, not that request for assessment matters. Exponentiation is correct affiliated, with the end goal that 2 ** 3 ** 4 assesses 3 ** 4 first, at that point raises 2 to the 81st force. Use enclosures on the off chance that you compose code this way.

On the off chance that you retain just the priority and associativity of the basic numerical administrators, you’ll be fine. Disentangle your code and you won’t need to remember other associativities. On the off chance that you can’t streamline your code (or in case you’re keeping up code and attempting to get it), utilize the center B::Deparse module to see precisely how Perl handles administrator priority and associativity.

The arity of an administrator is the quantity of operands on which it works. A nullary administrator works on zero operands. An unary administrator works on one operand. A twofold administrator works on two operands. A three-parted administrator works on three operands. A listary administrator works on top-notch of at least zero operands.

Conclusion

Hence, we would like to conclude by stating that you have perceived how Perl oversees setting through its administrators. To comprehend Perl completely, you should see how administrators communicate with their operands. Each administrator has a few significant qualities which administer its conduct: the quantity of operands on which it works, its relationship to different administrators, the settings it authorizes, and the grammar it gives.

How Sprintf Function Works In Perl With Examples?

Introduction to Perl sprintf

Web development, programming languages, Software testing & others

Syntax

The Perl script has the default variables, keywords, and functions to handle the applications. The sprint function uses some formats like string-based user input values in the data list. Using some conversion specifiers, the string format is handled by the corresponding user inputs.

#!/usr/bin/perl $variable name = sprintf( '%conversion specifiers', input values);

—some Perl script codes based on the application requirements—

The above codes are the basic syntax for creating applications with the help of the sprint function. The variables and scalar datas will be considered as the singular type of inputs. It may be the data types like strings or integer numbers.

How sprintf function works in Perl?

The Perl script has its own sprintf formats that can be used while the function it been executed in the application, and it can be emulated and similar to the other programming languages like c etc. The printf method is used to creating the user inputs as formatted one on the screen. Still, the sprintf method will be executed and accepts only the same type of arguments. Still, it will be returned using the formatted strings instead of printing options it can get and retrieved the user inputs with string formats. It will print the data to the files, or any other storage devices will be sent to via network protocols and concepts like emails, chats, etc.

The sprintf function will use some format specifiers, and these formats will mainly handle all the user input data types; the string formats will take and count the number of tokens that describe and handle user input values. Generally, the printf() function is the number of tokens that describe and print the variables whatever we needed in the project. Each variable format specifiers will start with the specifier like a % and also moreover the zero or n number of the optional modifiers ending with the conversion specifiers like if we use %d as the format specifier of the method while executing the method, the variable value will automatically convert to the user input values like integer numbers. We can insert these values to the format string values, and the library functions like sprint will use some default exponents, including the scientific notations like %e, %E, etc., for each input value; the numbers also calculated using the modules with exponents.

The method having the default parameters using some indexes will be both implicit and explicit conversions. In default, sprintf() function will use some type of arguments in the numbers list; this will be allowed with the type of arguments which has both valid and invalid number formats, so the invalid identifiers are in the out of the order formats which we have used the same input as the looping conditions.

The flags are also set as the valid input identifiers; the % symbol will be used for the convert the input conversions while the input values like numbers are the more set of precisions when it’s incremented in the looping conditions. For Each set of vector flags, the integer number values are interpreted with the supplied set of string values; those values are allotted for each character in the input strings Because the method will be calculated only the scalar type of input values which are to be passed in the method as the argument, so the Perl script which has applied the user input formats for each set of number integers those integer values are manipulated and concatenated using the string values which has to get the execution results after the method. The vector flags are also generally displayed using some sorting order values of the specified characters in the main, arbitrary set of strings.

Examples of Perl sprintf Example #1

Code:

$valu1 = sprintf("%03d %1$d", 'siva'); $valu2 = sprintf("%03d%1$d", 'raman'); $valu3 = sprintf("%04d%1$d", 'sivaraman'); $valu4 = sprintf("%05d", 'arun'); $valu5 = sprintf("%06d", 'kumar'); $valu6 = sprintf("%07d%d%1$d", 'arunkumar'); $valu7 = sprintf("%08d%1$d", 'hareesh'); $valu8 = sprintf("%09d", '898589'); $valu9 = sprintf("%10d", '2-80'); $valu10 = sprintf("%11d", '4356'); $valu11 = sprintf("%12d", '`142'); $valu12 = sprintf("%13d", '98765'); $valu13 = sprintf("%14d", 'fg5'); $valu14 = sprintf("%15d%d%1$d", '45grea'); $valu15 = sprintf("%16d", 'AF34r'); $valu16 = sprintf("%17d", 'ASCfdfd45'); print "$valu1n$valu2n$valu3n$valu4n$valu5n$valu6n$valu7n$valu8n$valu9n$valu10n$valu11n$valu12n$valu13n$valu14n$valu15n$valu16n$valu17";

Output:

Example #2

Code:

use strict; use warnings; my $valu1 = sprintf("%b", 198988721); my $valu2 = sprintf("%b", 79587); my $valu3 = sprintf("%b", 90247548); my $valu4 = sprintf("%x", 79587); my $valu5 = sprintf("%4f", 198988721); my $valu6 = sprintf("%.2f %.3f", 1989.88721, -678.786); my $valu7 = sprintf("%x", 90247548); my $valu8 = sprintf("%x", 198988721); my $valu9 = sprintf("%x", 732); my $valu10 = sprintf("%x", 82349587); my $valu11 = sprintf("%x", 192374654790439); my $valu12 = sprintf("%x", -912837459072980); my $valu13 = sprintf("%x", 12398457); my $valu14 = sprintf("%x", 923948577); my $valu15 = sprintf("%b", 192374654790439); my $valu16 = sprintf("%x", 109238475); my $valu17 = sprintf("%x", 2349857); my $valu18 = sprintf("%x", 12938475); my $valu19 = sprintf("%x", 2938475); my $valu20 = sprintf("%x", 102394875); my $valu21 = sprintf("%x", 8192384578); my $valu22 = sprintf("%x", 712394857); my $valu23 = sprintf("%x", 19238475); print "$valu1n$valu2n$valu3n$valu4n$valu5n$valu6n$valu7n$valu8n$valu9n$valu10n$valu11n$valu12n$valu13n$valu14n$valu15n$valu16n$valu17n$valu18n$valu19n$valu20n$valu21n$valu22n$valu23n";

Example #3

Output:

Conclusion

In the Perl script, we have used the default methods in different scenarios; among these, the sprintf is the value conversion using format specifiers. The values precision will be of any data types like integer numbers, decimal, and floating-point numbers, but it always returns the string characters as a result.

How Random Works In Kotlin With Examples?

Introduction to Kotlin Random

Web development, programming languages, Software testing & others

Syntax of Kotlin Random

In kotlin language has many default classes, methods and keywords for to implement the application. Like Random is one of the abstract class types, and it is used to generate the pseudo-random number generator; it has its own keyword and its syntax for to perform the operations in the code.

fun name() Assert.assertTrue((0..1000).all{   (0..10).contains((0..10).random()) } ) Assert.assertFalse(((0..1000).all{ (0..10).contains((0..10).random()) } } { }

The above code is the basic syntax for utilising the random class and its method for to calculate the pseudo-random number generations.

How Random Works in Kotlin?

The random number generation is like a pseudo number sequence; it generates automatically and random manner.  It returns a repeatable and sequence order with seeded on the data type like two generators with the same seed produce for sequence number range also the same version of kotlin runtime polymorphism. With the help of a random number generator algorithm, the numbers are calculated, generating sequence. While on the JVM machine, the random number generator is not the thread-safe, and it does not invoke it with the multiple thread sequences; it is also arranged with the synchronization.

So that two seeds can produce with the same sequences of values within the kotlin runtime versions. Based on the algorithm, the user inputs are accepted with initial ranges that can be the seed or key so we apply that seed in the sequence manner with some mathematical operations for to generate the output results. So that output we named it random number use that also results in random number will give the next set of iterations to continue their tasks. So it’s not possible for generating the true random numbers. So it has two types like non-deterministic random number generator and true random number generator. Non-deterministic random number generators are also called as pseudorandom number generators.

Examples of Kotlin Random

Given below are the examples of Kotlin Random:

Example #1

Code:

package one; import java.util.Random val rd = Random() object Tests { var infos = "Welcome To My Domain its the first example that related to the kotlin random function" } val vars = arrayOf("'Your first inputs' - Its the Monday", "'The second inputs' - Its the tuesday", "'The third inputs' - Its the Wednesday", "'The fourth inputs' - Its the Thursday", "'The fifth inputs' - Its the Friday", "'The sixth inputs' - Its the Saturday ","'The seventh inputs' - Its the Sunday", "'Every object has the separate attributes and its elements' - Programming language") val vars1 =  arrayOf("'Your eight inputs'- programming concepts and its implemnetations","'The most important things in the life are the day you are born and the day you find out why'- what is the reason for this") val vars2=arrayOf("'The life is more precious things and don’t wasted every single minute in a day you are born and the day you find out why.' - Great legend","'Great lengends are more powerful when compare to the others life are the day you also born with the silver spoon' - The Legendary things") fun res(at1: Int, at2: Int) = rd.nextInt(at2-at1+1)+at1 println(vars1[res(0,(vars1.size)-1)]) println(vars[res(0,(vars.size)-1)]) println("Thank you users have a nice day users keep spending your valuable time with us") }

Output:

In the above example, we used the arrayOf() method in the variable, and we validated the integer number and generate it randomly.

Example #2

Code:

package one; import java.util.Random fun demo(strleng: Int) : String { println("Welcome To My Domain its the second example that related to the kotlin random concepts") val inpstr = "ABCDEFGHIJKLMNOPQRSTUVWXTZabcdefghiklmnopqrstuvwxyz0123456789" return (1..strleng) .map { inpstr.random() } .joinToString("") } fun second(){ lst.add("The input is entered on the text box is: 0") lst.add("The input is entered on the text box is: 1") lst.add("The input is entered on the text box is: 2") lst.add("The input is entered on the text box is: 3") lst.add("The input is entered on the text box is: 4") lst.add("The input is entered on the text box is: 5") lst.add("The input is entered on the text box is: 6") lst.add("The input is entered on the text box is: 7") lst.add("The input is entered on the text box is: 8") lst.add("The input is entered on the text box is: 9") for(i in lst) print("The arryList are iterated please find your input values $i ") } fun main() { val strleng = 13 val res = demo(strleng) println(res) }

Output:

Example #3

Code:

package one; import java.util.Random interface infy  { fun third(strl:String) : String{ println("Welcome To My Domain its the third example that related to the kotlin random concepts") val inpstr = "Valuable Inputs must be entered and its more important for validation with both front and back end" return (inpstr) .map { inpstr.random() } .joinToString("") } } class Test{ fun four(leng:Int):String {println("Your operations are starting") val chs = ('a'..'z') + ('A'..'Z') + ('0'..'9') return (1..leng) .map { chs.random() } .joinToString("") } } fun main() { val num=17 val strs=Test() println(strs.four(num)) println("Your operations are ended") }

Output:

In the final example, we used class and interface are additionally added for to perform the random() function.

Conclusion

In the kotlin language, mobile applications are intermittently added some default methods to perform the user tasks according to the software requirement. But some mathematical operations are needed to be performed without affecting the application functionality like that random is one of the default class and methods for performing these operations.

Working Of Bless() Function In Perl With Examples

Introduction to Perl bless function

Web development, programming languages, Software testing & others

Working of bless() function in Perl with examples

In this article, we will discuss a built-in function where to make the program understand that the variable can be made an object of a particular class in Perl, where this function is known as the bless() function. Unlike in other programming languages, Perl creates an object similar to creating or declaring variables. Therefore the Perl programming language provides a built-in function called bless() function, which makes the variable look like an object of the particular class that it belongs to.

Now let us see the syntax and examples of how the bless() function works in the below example.

Syntax:

bless var_ref, class_name;

Parameters:

var_ref: this parameter refers to the variable as an object of the class whose class name is specified.

class_name: This parameter specifies the class name to which the object is created by marking the variable reference as an object of this class specified in this parameter.

This function can take only var_ref as an argument also, and this function returns the reference of the marked variable as a reference to an object blessed into a particular or specified class name as specified in the arguments passed to the function.

Examples

Now let us see a simple example of demonstrating the bless() function in the below section.

Example #1 use strict; use warnings; print "Demonstration of bless() function in Perl."; print "n"; print "n"; package student_data; sub stud { my $class_name = shift; my $var_ref = { }; print "The bless() function is now implemented:"; print "n"; bless $var_ref, $class_name; return $var_ref; } print "Object creation"; print "n"; print "n"; my $info = stud student_data("Alen","Python",32); print "The student's name is :"; print "n"; print "n"; print "The course name student taken is:"; print "n"; print "n"; print "The student's age is :"; print "n"; print "n";

Output:

In the above program, we can see we have defined class “stud” using a keyword package in Perl. Then we created a subroutine to print the student’s details. In this variable, we are referring each variable to the class name using the variable reference to object creation and class name as arguments in the bless() function in the above program. Then we are printing each value of the objects created.

Now we will see bless function taking only one argument and two arguments in the example below.

Example #2 use strict; use warnings; print "Demonstration of bless() function in Perl."; print "n"; print "n"; package student_data; sub stud { my $class_name = shift; my $var_ref = { }; print "The bless() function is now implemented:"; print "n"; bless $var_ref; return $var_ref; } package Employee; sub emp { my $class2 = shift; my $var_ref2 = { }; bless $var_ref2, $class2; return $var_ref2; } print "Object creation"; print "n"; print "n"; print "Bless function takes only one argument:"; print "n"; print "n"; my $info = stud student_data("Alen","Python",32); print "The student's name is :"; print "n"; print "n"; print "The course name student taken is:"; print "n"; print "n"; print "The student's age is :"; print "n"; print "n"; print "Bless() function takes two argument:"; print "n"; print "n"; my $per_info = emp Employee("Ram", "Shukla", 343); print "The employee's name is :"; print "n"; print "n"; print "The employee's second name student taken is:"; print "n"; print "n"; print "The employee's employee number is :"; print "n"; print "n";

Output:

In the above program, we can see we have declared two classes “student_data” and “Employee” wherein the class “Student_data” we have defined function bless() with the single argument so when the variables reference is only passed, it will by default, take only the values of its current class but not of the “employee” class.

Conclusion

In this article, we conclude that the bless() function is a built-in function in Perl for marking the variables reference to object creation which belongs to the particular class with its class name specified as an argument in the bless() function. In this article, we have seen examples of bless() function taking two arguments and what happens if there are two classes and the class name is not specified as an argument in the function, which will, by default, take the current class name.

How Django Mail Works With Programming Examples

Introduction to Django Mail

Apart from the SMTP mail connectivity offered by Python, Django also provides the chúng tôi library for handling email requests. Any email-oriented process can be handled very flexibly by this library. We can use this library to send emails to external users, website admins, and website managers; emails with attachments and even emails to a bulk set of mass users can be triggered. Adjusting the email delivery process in Django-based frameworks can easily meet individual needs and significantly speed up the process.

Start Your Free Software Development Course

Web development, programming languages, Software testing & others

How does Django Mail work?

Given below shows how Django Mail works:

1. To connect the email setup to Django, the below-listed email configurations should be in the chúng tôi file.

EMAIL_HOST − SMTP server.

EMAIL_HOST_USER − SMTP server login credentials.

EMAIL_HOST_PASSWORD − SMTP server password credentials

EMAIL_PORT − port of SMTP server.

EMAIL_USE_TLS or _SSL − True if secure connection.

Code:

EMAIL_USE_TLS = True

a. EMAIL_BACKEND

The email backend protocol used is referred to in the EMAIL_BACKEND variable. Some of the protocols are SMTP, SMTPS, IMAP, etc. By default, Django utilizes the SMTP protocol. Here, we explicitly mention the SMTP representation through the variable ‘django.core.mail.backends.smtp.EmailBackend’.

b. EMAIL_HOST c. EMAIL_PORT

The email port refers to the email provider’s port which is opened for SMTP connectivity.

Example: for yahoo the port number is 465

d. EMAIL_USER

Please provide the username for the email account that we need to connect.

Example: [email protected]

e. EMAIL_PASSWORD

This represents the password of the corresponding email account.

f. EMAIL_USE_TLS

This parameter is used to mention whether TLS secure connection needs to be turned on or not.

2. The next critical step is using django.core.mail.

The chúng tôi library has four methods for handling emails.

a. send_mail()

Syntax:

send_mail(subject, message, from_email, recipient_list, fail_silently=False, auth_user=None, auth_password=None,connection=None, html_message=None)

Description:

This method sends the email and posts the number of messages delivered.

b. send_mass_mail()

Syntax:

send_mass_mail(datatuple, fail_silently=False, auth_user=None, auth_password=None, connection=None)

Description:

Sends mail to a wide set of people; the data tuple combines the below elements.

(subject, message, from_email, recipient_list)

c. mail_admins()

Syntax:

mail_admins(subject, message, fail_silently=False, connection=None, html_message=None)

Description:

Sends mail to side admins as the admin names are declared in the ADMIN settings.

d. mail_managers()

Syntax:

mail_managers(subject, message, fail_silently=False, connection=None, html_message=None)

Description:

Sends mail to side managers as the Manager names are declared in the MANAGER settings.

Example:

Code:

Note: The major difference between send_mail() and send_mass_mail() is for send_mass_mail(), the server connections remain permanent, whereas for send emails, it is established for every send mail call.

3. Creating a temporary smptp server within the system for debugging purposes.

python -m smtpd -n -c DebuggingServer 127.0.0.1:8001

Output:

Examples of Django Mail

Given below are the examples mentioned :

Example #1

The email is captured in the temporary SMTP server in the first example. The server is set up to hear at port 8001. Also, the Django server localhost id (127.0.0.1) is set as the hostname here.

a. Make the email configurations in the chúng tôi file.

EMAIL_BACKEND = ‘django.core.mail.backends.smtp.EmailBackend’ EMAIL_HOST = ‘127.0.0.1’ EMAIL_PORT = 8001 EMAIL_HOST_USER = ” EMAIL_HOST_PASSWORD = ” EMAIL_USE_TLS = True

b. Set the view for email processing. The send_email() method triggers the email by tagging it with three fields captured from the front-end webpage through the form.

Code:

def email_sending(request): email = emailform() if request.method == 'POST': email_id =  request.POST['email'] email_subject =  request.POST['email_subject'] email_message =  request.POST['email_message'] res = send_mail(email_subject,email_message,'[email protected]',[email_id],fail_silently = False) return HttpResponse('%s'%res) return render(request, 'emailpage.html',{"email":email})

chúng tôi

Code:

from django import forms class emailform(forms.Form): email = forms.EmailField() email_subject = forms.CharField() email_message = forms.CharField(max_length = 2000)

c. Formulate the template for preparing the webpage.

Code:

{% load static %} body { background-image: url(“{% static ‘admin/img/background.jpg’ %}”); background-color: #acccbb; } .myDiv { border: 5px outset red; background-color: lightblue; text-align: center; font-family: “Comic Sans MS”, cursive, sans-serif; font-size: 14px; letter-spacing: 2px; word-spacing: 1.8px; text-align: left; color: #02071C; font-weight: 200; text-decoration: none; font-style: normal; font-variant: normal; text-transform: capitalize; } {{ email.as_p }} {% csrf_token %}
