In python,Using secure passwords is extremely important, given that many of us store important information online. Write a function that accepts a password as a parameter and validates it, according to these rules:

At least eight characters long

Includes at least one uppercase and one lowercase letter

Includes at least one digit

Write a program that uses this function to check passwords. The program should prompt the user for a password and then check to ensure that it conforms to the rules. If a password does not meet the requirements above, the program should prompt again until it does.
