Well since you didn't give an error I'm going to assume your problems 
are as follows:
* Use raw_input() instead of input() # input evals the input received.
* pass prompt as the argument to raw_input so that your prompt gets set 
# might want to give prompt a default value
* password.lower() so Y, YE, YES, N, NO, NOPE also work for input
