When using the url http://docs.python-requests.org/en/latest/, it redirects to https://2.python-requests.org//en/latest/ (notice the extra / before en). This causes a HTTP 404.

from oauthlib.oauth2 import BackendApplicationClient
from requests_oauthlib import OAuth2Session
client_id = '<redacted>'
client_secret = '<redacted>'
token_url = 'https://login.microsoftonline.c
