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.

I have provided PYTHON CODE along with CODE SCREENSHOT and 3 OUTPUT SCREENSHOTS---------

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.

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.

Write a function called HW7B, which returns a String. This String is the value of word 8 of the second paragraph beginning with Runtime of section 14.1 of page 544 of the course textbook (Introduction to Java programming Comprehensive version 2013 Online Walter J. Savitch ). This word begins with the letter ‘r’. This book can be accessed via the library link reachable via the courses ‘Library page’.

Write a function called singleDigits() that has a single parameter representing a four digit number (must be a four digit number). The function should return each of the digits that make up the four digit number. singleDigits(1234) >>> First: 1, second: 2, third: 3, fourth: 4 Your code should use % and //. The program should have at least two functions (main and one more). Style (names of variables/parameters/arguments, indentation) needs to be correct.

Create a function named fnTuition that calculates the tuition for a student. This function accepts one parameter, the student ID, and it calls the fnStudentUnits function that you created in task 2. The tuition value for the student calculated according to the following pseudocode: if (student does not exist) or (student units = 0) tuition = 0 else if (student units >= 9) tuition = (full time cost) + (student units) * (per unit cost) else tuition = (part time cost) + (student units) * (per unit cost) Retrieve values of FullTimeCost, PartTimeCost, and PerUnitCost from table Tuition. If there is no student with the ID passed to the function, the function should return -1. Code two tests: 1) a student who has < 9 student units, and 2) for a student who has >= 9 student units. For each test, display StudentID and the result returned by the function. Also, run supportive SELECT query or queries that prove the results to be correct.

In Python, please Write a program that asks user to enter email address. Program then checks and prints whether email entered by the user is valid. Structure your program to have two functions: isEmailValid function that takes a string as parameter and returns True or False depending on whether the input string matches all the requirements of a valid email listed main function that repeatedly prompts the user for the email address, calls isEmailValid method passing the user entered string, saves the returned value reports whether the email is valid or not depending on the returned value. asks user if he/she wants to continue. If so, repeats above steps. Otherwise ends the program. Use the recommended strategy of calling the main function use "if __name__ ..." format. Email should be of the form first.last@bellevuecollege.edu. It should have a '.' a '@' should end with "bellevuecollege.edu" index of first '.' should be less than the index of '@' there should be only one '.'…
