First thing you are doing wrong: you are re-typing the script instead of
copying and pasting it. There's at least one error in your script below: a
missing colon. How many other errors did you make when retyping? There's no
way for us to tell.

Second thing you are doing wrong: keeping the exception traceback a secret
from us. How are we supposed to diagnose the error when we can't see what
the error is?

Even if we wanted to run your code, we can't: we'll get a completely
different error, since we don't have access to your network and user
account.

If there is no exception traceback, is there any output at all?

Again, don't type it from memory, COPY and PASTE the output as you see it,
exactly. If you remove any private information (like a plain text password)
make it obvious that has been removed by replacing it with a string of
asterisks **** .
