How to use gcloud auth list in python

Question

We could run "gcloud auth list" to get our credentialed account, and now I want to do the same thing in my python code, that is checking the credential account by API in python. But I didn't fine it..... Any suggestion?

More information is: I want to check my account name before I create credentials

CREDENTIALS = GoogleCredentials.from_stream(ACCOUNT_FILE)
CREDENTIALS = GoogleCredentials.get_application_default()

gcloud stores credentials obtained via

• gcloud auth login
• gcloud auth activate-service-account

in its internal local database. There is no API besides gcloud auth list command to query them. Note that this is different (usually a subset) from the list of credentials in GCP.

Credentials used by gcloud are meant to be separate from what you use in your python code.

Perhaps you want to use https://cloud.google.com/sdk/gcloud/reference/iam/service-accounts/keys/list, there is also API for that https://cloud.google.com/iam/docs/creating-managing-service-accounts.

For application default credentials you would download json key file using developer console https://console.cloud.google.com/iam-admin/serviceaccounts/project?project=YOUR_PROJECT or use gcloud iam service-accounts keys create command.

There is also gcloud auth application-default login command, which will create application default credential file in well known location, but you should not use it for anything serious except perhaps developing/testing. Note that credentials obtained via this command do not show up in gcloud auth list.
