I might have missed something, but don't you want to be using BaseException
as your class/type? Also, Checking isinstance() between two classes isn't
likely to work, I don't think.
Both the 2.7 and 3.6 docs indicate that BaseException is the base class for
all built-in exceptions:
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.
