PyChecker (http://pychecker.sourceforge.net/) will help you spot this kind of thing. For example consider typo.py: def f(): x = 1 y = 1 if 0 == 1: print a else: print x+y When you run PyChecker on typo.py it will issue the following warning: typo.py:5: No global (a) found Jimmy -- http://mail.python.org/mailman/listinfo/python-list
