Category: Python Interpreter Core Group: Python 2.4 Status: Open Resolution: None Priority: 5 Submitted By: Stefan Seefeld (stefan) Assigned to: Nobody/Anonymous (nobody) Summary: two strings holding the same value have different id Initial Comment: I'v run into a problem with a program that expects a string to be either 'resource' or 'test': type = ... if type is "resource": do_something() elif type is "test": do_something_else() The above comparison using 'is' works fine with python 2.3, but fails with python 2.4. Unfortunately I wasn't able to isolate the problem. To reproduce: Install qmtest from http://www.qmtest.com on windows xp with python 2.4 (I don't know yet whether other platforms are affected, too). Then follow the instructions from http://www.codesourcery.com/public/qmtest/qm-2.2/manual.html up to section 2.2 'Starting the Graphical Interface'. In the browser, click on the 'exec1' test, and you'll get an 'UnboundLocalError' because the application logic didn't expect some comparison to fail. The failed comparison in question is 't is "test"', which returns 'False' even though t == "test". ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1086096&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
