New submission from Daniel543 <superplayer_...@163.com>: Python 2.7.3 (default, Apr 20 2012, 22:44:07) [GCC 4.6.3] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> a = ['1'] >>> b = [] >>> c = a >>> b.append(a) >>> a ['1'] >>> b [['1']] >>> c ['1'] >>> a = ['2'] >>> c.extend(a) >>> b [['1', '2']] >>> c ['1', '2'] >>> a ['2'] >>>
Is this wrong? I think the "b" should not change. ---------- components: None messages: 159807 nosy: Daniel543 priority: normal severity: normal status: open title: extend() puzzled me. type: behavior versions: Python 2.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue14707> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
