[Python] Google Service account authentication for API call using python

Wanted to call out one GCP api from my python code, following is that method -

import google
from google.oauth2 import service_account
import google.auth.transport.requests
import requests

def get_window(self):
credentials = service_account.Credentials.from_service_account_file(
self.default_credentials, scopes=['https://www.googleapis.com/auth/cloud-platform']
)
request = google.auth.transport.requests.Request()
credentials.refresh(request)

# Make an authenticated API request
request_url = "https://sqladmin.googleapis.com/v1/projects/my-projectid/instances/my-instanceid"
headers = {"Authorization", f"Bearer {credentials.token}"}
req = requests.get(request_url, headers=headers)
print(req.text)


When I call this method, following is the response:

request = google.auth.transport.requests.Request()
AttributeError: module 'google.auth.transport' has no attribute 'requests'
