| This patch lets the description of the xrange builtin function include the recently by Alex Martelli on python-dev described notion that itertools.repeat(None, n) may be a lot faster than range() or xrange(). |

| Logged In: YES user_id=80475 Though "for _ in itertools.repeat(None, n):" offers a small speed advantage, it is not as readable as "for i in xrange(n):" which should remain the preferred looping idiom. The purpose of itertools.repeat() is to supply repeated arguments to imap() and izip(). Its secondary purpose is to provide a memory friendly version of "[obj] * n". Using it as a speedup for xrange() should only be used in rare situations where a slight performance gain is essential. |
