Okay if you - unlike me - did actually read the documentation of the Python traceback module you probably know that what I wrote here can be archived much easier if you just do this:

try:
    1 / 0
except:
    import traceback
    traceback.print_exc()

And if you want to do something with your traceback like send it per mail you can do like so:

try:
    1 / 0
except:
    import traceback
    import StringIO

    fp = StringIO()
    traceback.print_exc(file=fp)
    print fp.getvalue()
