Google-oauth inside Jupyter laptop

Question

I am using google oauth2client, and the code from the example:

flags = argparser.parse_args()
credentials = run_flow(flow, storage, flags)

Everything works in Python interactive or IDE, but if I try to use the code from Jupiter Notebook, I got an exception.

Inside Jupiter Noteboo I try simply:

    from oauth2client.tools import argparser
    argparser.parse_args()

and got:

usage: __main__.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}]

From the documentation for ArgumentParser.parse_args(), “By default, argument lines are taken from sys.argv[...],” in which case the command line arguments sys.argvare the ones that created the Jupyter laptop server process. As a workaround, assuming you don't need to use any flags, you can replace

flags = argparser.parse_args()

with

flags = argparser.parse_args([])

, :

flags = argparser.parse_args(['--auth_host_name=example.org', '--auth_host_port=1234'])
