Using APIs with Python Requests Module. Tidbits on using requests.
GitHub v3 API. The GitHub API is fairly clean.
Creating an access token for command-line use. Most uses of the GitHub API need to do the work on authenticated logins, and the easiest way to do that is to create an access token to avoid needing to implement the full OAuth flow.
