I'm using the code from here: Sending email via gmail & python Step 3, (my version shown below)

with the difference from the other answer is on line 19, I've modified variable [home_dir] to:
home_dir = "C:\\Users\\kelvi_000\\Documents\\Jupyter Notebooks\\"
In addition to:
#credentials = store.get()
credentails = False
if True: #not credentials or credentials.invalid:
commenting out the declaration for [credentials] and modifying the if credentials aren't valid part. (lines 25-27)
Now the problem is:
usage: ipykernel_launcher.py [--auth_host_name AUTH_HOST_NAME]
[--noauth_local_webserver]
[--auth_host_port [AUTH_HOST_PORT [AUTH_HOST_PORT ...]]]
[--logging_level {DEBUG,INFO,WARNING,ERROR,CRITICAL}]

An exception has occurred, use %tb to see the full traceback.
SystemExit: 2
C:\Users\kelvi_000\Anaconda3\lib\site-packages\IPython\core\interactiveshell.py:2918: UserWarning: To exit: use 'exit', 'quit', or Ctrl-D.
warn("To exit: use 'exit', 'quit', or Ctrl-D.", stacklevel=1)
No stack trace, no line numbers, no ipykernel_launcher... just this stupid error that doesn't show anything when googled...
Using python3
update: I've tracked the problem down to the line:
credentials = tools.run_flow(flow, store)
in the function
get_credentials
