[GitHub] [airflow] potiuk commented on pull request #17576: Add pre/post execution hooks

potiuk commented on pull request #17576:
URL: https://github.com/apache/airflow/pull/17576#issuecomment-986363233


   Another possibly interesting use case for pre_execute:

   Basically adding a "session" attribute that would authorize the call with PythonOperators - defined at a DAG level. Pretty useful IMHO: 
   
   ```
   def authorize(self):
         CREDENTIALS, _= google.auth.default(scopes=['https://www.googleapis.com/auth/cloud-platform'])
         self.session = AuthorizedSession(CREDENTIALS)
   ```
