python, basic question on loops

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"

From stackoverflow

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

  contagious : beat me to it. this is the one.

  kigurai : Haha, I am too slow as well :)

• keepLooping = True
  while keepLooping:
    # do stuff here
  
    # Prompt the user to continue
    q = raw_input("Keep looping? [yn]: ")
    if not q.startswith("y"):
      keepLooping = False
  

  S.Lott : +1: formal exit condition without a break (Also, I removed the extra print)

  HanClinto : Aaah, thanks S. Lott. I was racing, and missed that one -- thanks! :)

• There are two usual approaches, both already mentioned, which amount to:

  while True:
      do_stuff() # and eventually...
      break; # break out of the loop
  

  or

  x = True
  while x:
      do_stuff() # and eventually...
      x = False # set x to False to break the loop
  

  Both will work properly. From a "sound design" perspective it's best to use the second method because 1) break can have counterintuitive behavior in nested scopes in some languages; 2) the first approach is counter to the intended use of "while"; 3) your routines should always have a single point of exit

  ΤΖΩΤΖΙΟΥ : Now, if only you kept the two code bits and removed the final three paragraphs, I promise I will upvote you ;)

  Jason L : There, I've made it more to the point. Just out of curiosity, was there something wrong with what I said or was it just how I said it?

• While raw_input("loop again? y/n ") != 'n':
      do_stuff()
