Error when using Custom Exception defined in a different python module.

[pillappa@hotmail.com]

Hi,

I am hitting this error consistently and don't know why it's
happening. I would like to define all exceptions for my project in one
file and use them across the project. Here's a sample -

exceptions.py -

class MyException(Sta ndardError):
def __init__(self, error):
self.myerror = error

tests.py -

from exceptions import *

class Test:
def __init__(self,f ilename):
if filename == "":
raise MyException("Ra ise custom error")

if __name__ == "__main__" :
test = Test("")


When the above is run, I get the following error -
NameError: global name 'MyException' is not defined

Thanks

When you get this kind of error, goto a python prompt
(type python at a command prompt, or click on IDLE)
and try this:

>>import exceptions
>>help( exceptions )

I got this response (clipped):

Help on built-in module exceptions:

NAME
exceptions - Python's standard exception class hierarchy.

Another common module name to avoid is "test".

Rob.
