By the way, Python has something similar to a function that temporarily interrupts execution but preserves state. It's called generator. Compare: >>> def f(): ... for i in range(3): ... return "<p>Long line with games</p>" ... >>> f() '<p>Long line with games</p>' >>> def g(): ... for i in range(3): ... yield "<p>Long line with games</p>" ... >>> g() <generator object g at 0x7fe9b3e7b690> >>> list(g()) ['<p>Long line with games</p>', '<p>Long line with games</p>', '<p>Long line with games</p>'] -- https://mail.python.org/mailman/listinfo/python-list
