get_oauth2_token.py

'''
    This script will attempt to open your webbrowser,
    perform OAuth 2 authentication and print your access token.

    It depends on two libraries: oauth2client and gflags.

    To install dependencies from PyPI:

    $ pip install python-gflags oauth2client

    Then run this script:

    $ python get_oauth2_token.py
    
    This is a combination of snippets from:
    https://developers.google.com/api-client-library/python/guide/aaa_oauth
