Yes/No function

A function to ask the user a yes/no question and return the result as a Boolean.

def yesno(question):
    answer = raw_input(question + " [yes/no]: ")
    if answer.lower() in ('y', 'yes'):
        return True
    elif answer.lower() in ('n', 'no'):
        return False

This is useful when you wish to ask the user before performing a task, for example "Would you like to exit?" could be programmed as follows:

while True:
    if yesno("Would you like to exit?"):
        break
