\# -*- coding: cp1252 -*- import inspector while True: userinput = input ("Give a string for testing: ") tulos = inspector.testme(userinput) if tulos == True: print ("This string fits for a password!") break else: print("The module says no.") has both numbers and letters, it should be accepted. In this case the module should return True. When the program works correctly, it prints the following: Example output: Give a string for testing: password The module says no. Give a string for testing: Pass 12 word 34 This string fits for a password! The verification of program output does not account for whitespace and is not case-sensitive (the least strict comparison level)
