It's testing something - specifically, whether or not the object wants to "feel true" or "feel false". It's up to the object to define what that means. Most of the time, it's exactly what you want. When it isn't, you can put an exact comparison. ChrisA -- http://mail.python.org/mailman/listinfo/python-list
