That's a bug in the application. You must not mix byte strings and unicode strings as dictionary keys. Whether or not the warning is produced: the behavior would still be fairly unpredictable, and vary with Python versions. > Of course it is only a warning, not a strong annoyance. This warning is deliberate. It tells the developer that something is broken about this application. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue13360> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
