   returning an empty list will do the work
   
   ```python
   def skip_things() -> str:
           if NOTHING:
               return []
           elif SOMETHING_WEIRD:
               return "task_2"
           else:
               return "task_3"
   
   branch_task = BranchPythonOperator(
       task_id='branch_task',
       python_callable=skip_things)
   
   task_2 = ...
   task_3 = ...
   
   branch_task >> [task_2, task_3 ]
   ```
