Catching user defined exceptions from foreign modules

[Derek Basch]

Everyone,
You were correct that the test1 module shouldn't have
worked at all. I needed to change the first line to:

from test2 import TestError, TryItOut

I had test2 open in the PythonWin IDE so it was
already in the namespace.
Which brings me back to my original issue of why it
works here and not in my larger module. Is it normal
to have to import user defined exceptions? I dont
rememeber having to import any of the built in
exceptions. So, here is the output of the fixed test1:

test2.TestError
fudge

Am I doing this all wrong?
Thanks,
Derek Basch

I don't even see why "test1" is working. You
explicitly import the 
exception by name, but you didn't bring in
"TryItOut"... That alone 
should have raised an exception.
