Snippet for "Integrating Google Calendar (G-suite) in Node" https://hackernoon.com/my-journey-integrating-google-calendar-g-suite-in-node-62fbc8596455

read_calendar_list.py

from google.oauth2 import service_account
from googleapiclient.discovery import build

SCOPES = ['https://www.googleapis.com/auth/calendar']
SERVICE_ACCOUNT_FILE  = './xxxxxxxxxxxx.json' # You should make it an environment variable

credentials = service_account.Credentials.from_service_account_file(SERVICE_ACCOUNT_FILE, scopes=SCOPES)
delegated_credentials = credentials.with_subject('melvin@xxxxxxxx.xx') 

service = build('calendar', 'v3', credentials=delegated_credentials) 

print(service.calendarList().list().execute())

It works for Google TASKS APi as well?
