Writing traceback of an exception into a log-file

[Dominique.Holzwarth at ch.delarue.com]

Hi all

I'm trying to write the traceback stack of an exception that is thrown into a log file, but currently all that's written is simply a "None" :-/

Here's some example code of what I'm doing:

Import traceback
class myException(Exception):
        def __init__(self):
                f = open('filename.txt', 'a')
                traceback.print_exc(file=f)
                f.close()

The file handling (opening etc) works ok (I'm using the same file in combination with a Logger() object too) but the string written to the file is effectively just a "None".

Could anyone explain to me how to properly use the traceback module with it's countless of functions? =)

Thanks in advance,
Dominique
