Yes I do, which is why I was demonstrating to Paul that his suggestion to use Exception instead of BaseException is not good enough. *wink* > Also, Checking isinstance() between two classes isn't > likely to work, I don't think. Indeed it doesn't, which is why I was demonstrating that Paul's suggestion to use isinstance instead of issubclass is not good enough. *wink* > Both the 2.7 and 3.6 docs indicate that BaseException is the base class for > all built-in exceptions: Indeed it is. Which is why in my original post I used BaseException. *eye spasms from winking too much* > https://docs.python.org/2/library/exceptions.html > https://docs.python.org/3/library/exceptions.html > > Of course, YMMV when dealing with user-defined exception classes. No, user-defined exceptions must derive from BaseException too. -- Steve “Cheer up,” they said, “things could be worse.” So I cheered up, and sure enough, things got worse. -- https://mail.python.org/mailman/listinfo/python-list
