I want to know which method should I call (and on which object) and how to call that method (required parameters and their meanings).
Thanks in advance!
import github g = github.Github(token) # or g = github.Github(login, password) repo = g.get_user().get_repo("repo_name") file = repo.get_file_contents("/your_file.txt") # update repo.update_file("/your_file.txt", "your_commit_message", "your_new_file_content", file.sha)
If you are using token then you should have at least repo scope of your token to do it. https://developer.github.com/v3/oauth/#scopes
