Connecting to Google Analytics API using Python

Question

I have tried to follow this tutorial to connect to Google Analytics API. I have followed the instructions, step by step. I have Python 2.7 installed on my computer. I have installed Google client library. When I run the program, i get the following error in the terminal:

Traceback (most recent call last):
  File "HelloAnalytics.py", line 6, in <module>
    from oauth2client.client import SignedJwtAssertionCredential
ImportError: cannot import name SignedJwtAssertionCredentials

The line 6 that it referring to is:

from oauth2client.client import SignedJwtAssertionCredentials

I am at a complete lost. I looked at others who have had the same error, here , here , and here , but the solutions did not work. I have some programming knowledge, but compared to many of you, I am a noob.

The full code is here:

"""A simple example of how to access the Google Analytics API."""

                service_account_email):

  else:
    print 'No results found'

  # Define the auth scopes to request.
  scope = ['https://www.googleapis.com/auth/analytics.readonly']

  # Use the developer console and replace the values with your
  # service account email and relative location of your key file.
  service_account_email = '<Replace with your service account email address.>'

    service_account_email)
  profile = get_first_profile_id(service)
  print_results(get_results(service, profile))


if __name__ == '__main__':
  main()

Any help or direction would be appreciated.

Answer 1

The source repository was recently updated, and the Hello Analytics Guides have since also been updated to make use of the new code:

from apiclient.discovery import build
from oauth2client.service_account import ServiceAccountCredentials

...
credentials = ServiceAccountCredentials.from_p12_keyfile(
    service_account_email, key_file_location, scopes=scope)

Where service_account_email is the email address of the service account you get from the dev console, and the key_file_locaiton is /the/path/to/key.p12 , and scopes are the scopes you need to grant to the service account.

Please remember to add the service account email address as an authorized user of the Google Analytics view (profile) to which you wish it to have access.
