I guess you could say that's true. I'm hardly an expert so I couldn't say there aren't other potential ramifications. (anyone?) But, as a rule I would declare the global variable always because 1) it makes my intention clear 2) if I later decided to modify the global variable, I would be less likely to introduce a bug by forgetting to declare it global. -- http://mail.python.org/mailman/listinfo/python-list
