Looping from 1 to infinity in Python

In C, I would do this: int i; for (i = 0;; i++) if (thereIsAReasonToBreak(i)) break; How can I achieve something similar in Python?
Using itertools.count: import itertools for i in itertools.count(start=1): if there_is_a_reason_to_break(i): break In Python 2, range() and xrange() were limited to sys.maxsize. In Python 3 range() can go much higher, though not to infinity: import sys for i in range(sys.maxsize**10): # you could go even higher if you really want if there_is_a_reason_to_break(i): break So it's probably best to use count().
