find and save not working

[kniknik2442]

I've been using proxybroker for about a day, and I am running through the examples and I noticed that the find_and_save example is not working for me. I'm inputting the exact same file but I added a line to fix the #147 error as well as import sys, but I don't think these are the issue.
FYI, I'm running 3.9.6 on a pretty scuffed version of the command prompt because I'm not admin on this computer and the command line is blocked so I'm using a workaround. That's beside the point, but I don't think this is the cause either.
So I'm entering this code:

and getting this output:

C:\Windows\system32\cmd.exe \Enter Command:python find_and_save.py

Anyone know how to fix this?
