Write a function named validate_variable_name() that asks the user to enter a variable name as a parameter as in the examples below. It thenchecks whether the variable name entered is a valid variable name based on the following rules:• A variable name can only have lowercase letters, digits and underscores.• A variable name cannot start with a number.A variable name cannot be any of the following keywords: 'False', 'None', 'True', 'and', 'as', 'assert', 'async', 'await', 'break', 'class', 'continue', 'def', 'del','elif', 'else', 'except', 'finally', 'for', 'from', 'global', 'if', 'import', 'in', 'is', 'lambda', 'nonlocal', 'not', 'or', 'pass', 'raise', 'return', 'try', 'while', 'with', 'yield'If the variable name breaks any of the above rules, then the function should print the message "This variable name is not valid." If it satisfies all theconditions then the function should print the message "This variable name is valid."For example:TestInputResultvalidate_variable_name() 2_marchEnter a variable name: 2_marchThis variable name is not valid.validate_variable_name() good_variable_name Enter a variable name: good_variable_nameThis variable name is valid.validate_variable_name() classEnter a variable name: classThis variable name is not valid.validate_variable_name() date_ReceivedEnter a variable name: date_ReceivedThis variable name is not valid.validate_variable_name() my-nameEnter a variable name: my-nameThis variable name is not valid.

Question

Write a function named validate_variable_name() that asks the user to enter a variable name as a parameter as in the examples below. It then
checks whether the variable name entered is a valid variable name based on the following rules:
• A variable name can only have lowercase letters, digits and underscores.
• A variable name cannot start with a number.
A variable name cannot be any of the following keywords: 'False', 'None', 'True', 'and', 'as', 'assert', 'async', 'await', 'break', 'class', 'continue', 'def', 'del',
'elif', 'else', 'except', 'finally', 'for', 'from', 'global', 'if', 'import', 'in', 'is', 'lambda', 'nonlocal', 'not', 'or', 'pass', 'raise', 'return', 'try', 'while', 'with', 'yield'
If the variable name breaks any of the above rules, then the function should print the message "This variable name is not valid." If it satisfies all the
conditions then the function should print the message "This variable name is valid."
For example:
Test
Input
Result
validate_variable_name() 2_march
Enter a variable name: 2_march
This variable name is not valid.
validate_variable_name() good_variable_name Enter a variable name: good_variable_name
This variable name is valid.
validate_variable_name() class
Enter a variable name: class
This variable name is not valid.
validate_variable_name() date_Received
Enter a variable name: date_Received
This variable name is not valid.
validate_variable_name() my-name
Enter a variable name: my-name
This variable name is not valid.

It is not sufficient to declare a variable by using "type" alone. A variable may be identified by the data type it uses as well as other properties. The next obvious step is to figure out how to utilize this concept to describe any particular variable?
