Some Web sites impose certain rules for passwords. Write a function that checks whether a string is a valid password. Suppose the password rules are as follows:

A password must have at least eight characters.

A password must consist of only letters and digits.

A password must contain at least two digits. Write a python 3.x program that prompts the user to enter a password and displays valid password if the rules are followed or invalid password otherwise( whether True or False). please also include comments for further understanding. Thanks
