New submission from paul rubin <[EMAIL PROTECTED]>: This is observed in Python 2.5.1, I haven't tried any later versions.
d = collections.deque(xrange(100000)) random.shuffle(d) is quite slow. Increasing the size to 200k, 300k, etc. shows that the runtime increases quadratically or worse. It's much faster to convert the deque to a list, shuffle the list, and make a new deque from the shuffled list. ---------- components: Library (Lib) messages: 74773 nosy: phr severity: normal status: open title: random.shuffle slow on deque versions: Python 2.5 _______________________________________ Python tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue4123> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
