Yeah, it's a small recipe I'm sure a lot of others have written as
well. My old version:
def iterwhile(callable_, predicate):
""" Like iter() but with a predicate instead of a sentinel. """
return itertools.takewhile(predicate, repeatfunc(callable_))
where repeatfunc is as defined here:
http://docs.python.org/library/itertools.html#recipes
I wish all of these little recipes made their way into itertools or a
like module; itertools seems a bit tightly guarded.
