Hello, Testing 2.3.4c1 I get: ... test_format /home/devel/compile/Python-2.3.4c1/Lib/test/test_format.py:19: FutureWarning: %u/%o/%x/%X of negative int will return a signed string in Python 2.4 and up result = formatstr % args ... Is this intended, or should it be solved? Regards Berthold -- bhoel at web.de / http://starship.python.net/crew/bhoel/
