New submission from Shawn Smout <silroq...@yahoo.com>: When calling the union method of a set with several arguments, if one of those sets is the original set, all arguments appearing after it are ignored. For example:
x = set() x.union(set([1]), x, set([2])) evaluates to set([1]), not set([1, 2]) as expected. As another example, since all empty frozensets are the same, frozenset().union(frozenset([1]), frozenset(), frozenset([2])) also evaluates to just frozenset([1]). The fix is trivial, so I'm attaching a patch. ---------- files: set_union.patch keywords: patch messages: 90925 nosy: ssmout severity: normal status: open title: set union method ignores arguments appearing after the original set Added file: http://bugs.python.org/file14565/set_union.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue6573> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
