No, DON'T check for the string to be true, check if it matches the 
requirements.  Word the question for the user's convenience, not the 
programming language's.  Don't ask for true and false, ask "Continue?" 
and accept "Y" or "N".  Or ask "Q for quit".  Or whatever.  Make your 
comparison case-insensitive, and permit one-character responses.

continue = "y"
while continue[:1].lower() == "y":
     do some work
     continue = raw_input("Do you want to continue (y/n)?"
