I don't know that I've ever used a language without such a loop construct. I know you can use a "while True:" and a "break" but that looks so kludgy.

(On the plus side, I don't know that I've seen another language with the while-else construction that Python has. That's kind of cool.)

You can do this:

Code:

while True:
   do something
   do some more
   a += 1
   If a >= 10:
      Break

That's the equivalent of

Code:

DO
   do something
   do some more
   a = a + 1
LOOP WHILE a < 10

I know you think it looks kludgy as did I, coming from a BASIC background, but if you use Python for a while you get used to it. Since Python programmers think in terms of While True, there's no incentive to change it.
