2. Password Test: For security reasons, computer passwords usually must meet certain requirements. Write a program (password_test.py) that checks if passwords entered by the user meet these security requirements: ➤ at least 6 characters ➤no spaces or tabs ➤ at least 1 upper-case letter ➤ at least 1 lower-case letter ➤ at least one digit ➤ at least one special character (not letter, digit, space, or tab) The program has two functions: fValidatePwd(pw) and main().

2. Password Test: For security reasons, computer passwords usually must meet certain requirements. Write a program (password_test.py) that checks if passwords entered by the user meet these security requirements: ➤ at least 6 characters no spaces or tabs at least 1 upper-case letter at least 1 lower-case letter at least one digit at least one special character (not letter, digit, space, or tab) The program has two functions: fValidatePwd(pw) and main(). fValidatePwd(): Takes a password as a parameter, tests it for the above requirements, and returns True if the password is valid, False if not. It can use any of Python's built-in string functions and methods. It should not print anything or ask the user for anything. main(): Displays the requirements for passwords, then asks the user to enter a password. After the user enters a password, main() calls fValidatePwd() to check if the password is valid. If fValidatePwd()) returns True, print "Password OK." If fValidatePwd()) returns False, print "Sorry, that is not a valid password." Count the number of valid passwords entered and the total number the user tried. Regardless of whether the password is valid or invalid, ask the user if they want to try another password (y or n). Validate user's response: if what user entered is not y or n, ask again for y or n. If the user enters y, loop back for another password. If the user enters n, the program prints "Your score: N valid passwords in M attempts." and quits.
