New submission from alejandro david weil <ten...@gmail.com>: Python's documentation includes 2 source codes for alternate xrange implementations, which, at least in my tests, give unexpected results.
# from file:///usr/share/doc/python2.6-doc/html/library/functions.html#xrange takewhile(lambda x:x<stop, (start+i*step for i in count())) and: # from: http://docs.python.org/library/functions.html?highlight=xrange#xrange islice(count(start, step), (stop-start+step-1)//step) I'll attach a file with source code showing that, and propose 3 different versions which seems to work fine. (I've prefer the first one, but python lacks of sign() function). ---------- assignee: docs@python components: Documentation files: test_xrange.py messages: 135159 nosy: docs@python, tenuki priority: normal severity: normal status: open title: documentation: alternate version of xrange seems to fail. versions: Python 2.6, Python 2.7 Added file: http://bugs.python.org/file21887/test_xrange.py _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue12003> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
