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 '.' before '@' it should contain non-empty first and last names

Question
- 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 '.' before '@'
- it should contain non-empty first and last names
Hints:
- Use find / in / endswith methods
- Remember that isEmailValid method has the user input string as the only parameter and returns a boolean value of True or False.
- If any one of the requirements is not met, it should return False. And should return True only if all the requirements are met.
- Clearly you will need to have many if conditions. Sequence them correctly.
