Raise Error in a Module and Try/Except in a different Module

[Issa-Ahmed SIDIBE]

I Have a function FUNC1 that is define in ModuleA. This function raise
an exception EXCP1 (raise EXCP1), with EXCP1 a global variable in
ModuleA.

In ModuleB, I have some classes that call FUNC1. I would like to catch
EXCP1 and make some processing. How can I do that.

I tried in Module B

import ModuleA
...
class():
   ...
   try: a = ModuleA.FUNC1
   except ModuleA.EXCP1: print 'catch'

But It does not work. What is wrong?
