Looping from 1 to infinity in Python

Question

In C, I would do this:

int i;
for (i = 0;; i++)
  if (thereIsAReasonToBreak(i))
    break;

How can I achieve something similar in Python?

Answer 1

def infinity():
    i=0
    while True:
        i+=1
        yield i


for i in infinity():
    if there_is_a_reason_to_break(i):
        break
