How can I connect to NWWS-OI in Python?

Question

I am trying to build a program that interfaces with the NWWS Open Interface, or NWWS-OI for short. This is a service that provides NWS products over XMPP. I have an account (you have to request it), but how can I use it in Python?

I looked up "nwws-oi python", and I found https://github.com/jbuitt/nwws-python-client/. However, this will not work, as the script is intended for Linux systems, but I need to run this on a Windows system! I couldn't find any other GitHub repositories when I looked up "nwws-oi python", so how can I do this? (I ideally want a solution using slixmpp.)

Edit: Already tried porting it to Windows! Whenever I try to run it, I get this error:

Edit 2: This is what happens when it runs without pyasn1 and pyasn1_modules:

INFO     Using SSL version: TLS
WARNING  Could not find pyasn1 and pyasn1_modules. SSL certificate COULD NOT BE VERIFIED.
INFO     JID set to: [username removed]@nwws-oi.weather.gov/6fus3pafx6
WARNING  Could not find pyasn1 and pyasn1_modules. SSL certificate expiration COULD NOT BE VERIFIED.
WARNING  Use of send mask waiters is deprecated.

Then it just hangs after this!
