python - check at the end of the loop if need to run again

Question

It's a really basic question but i can't think at the second. How do i set up a loop that asks each time the function inside runs whether to do it again. So it runs it then says something like;

"loop again? y/n"

Answer 1

while True:
    func()
    answer = raw_input( "Loop again? " )
    if answer != 'y':
        break
