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.

Transcribed Image Text: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.
