How to get current account name in google colab - google-colaboratory

Question

For example, if my current Colab instance is signed in as
myColab#gmail.com
Is it possible to get the name "myColab" in ipython?
What is the command to do this?
I want to do this because I may run two Colab, and they generate files, I want to tag these files with Colab account name, so I know which account generate these files.

Answer 1

By default, the backends are not authenticated for any particular user. But, if you've gone through through the gcloud auth flow, you can retrieve the email address like so:

The key snippet is:
import requests
gcloud_token = !gcloud auth print-access-token
gcloud_tokeninfo = requests.get('https://www.googleapis.com/oauth2/v3/tokeninfo?access_token=' + gcloud_token[0]).json()
print(gcloud_tokeninfo['email'])

Answer 2

Or just run following:
!gcloud config get-value account

Answer 3

I was trying to get the current user logged in via the GDrive authenticaiton. I do not wish to push another authentication, just to record the name. I believe OP was attempting the same thing.
My theory was, login with google drive, create a file, then read the file's creator. This does not function as intended, it only returns root:root. But it might spark an idea how to make this work in someone who knows more about python and colab then me.
If you create the file in the directory MyDrive, GDrive can see the file and it says owner is Me, hovering over me shows the email account. GDrive knows who made it. I can just not figure out how to make colab output the real file owner, even for files already existing in MyDrive. I assume it is something to do with the mount being symbolic, but.. there HAS to be a way.
Code
print("test", file=open("owner.txt", "a"))
from pathlib import Path
path = Path("owner.txt")
owner = path.owner()
group = path.group()
print(f"{path.name} is owned by {owner}:{group}")
Output
owner.txt is owned by root:root
