------------------------------------

             Summary: Code example in docs has unnecessary DAG>>Operator 
assignment
                 Key: AIRFLOW-882
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-882
             Project: Apache Airflow
          Issue Type: Improvement
          Components: docs
            Reporter: Daniel Huang
            Assignee: Daniel Huang
            Priority: Trivial


The docs currently say:

{code}
We can put this all together to build a simple pipeline:

with DAG('my_dag', start_date=datetime(2016, 1, 1)) as dag:
    (
        dag
        >> DummyOperator(task_id='dummy_1')
        >> BashOperator(
            task_id='bash_1',
            bash_command='echo "HELLO!"')
        >> PythonOperator(
            task_id='python_1',
            python_callable=lambda: print("GOODBYE!"))
    )
{code}

But the {{dag >> ...}} is unnecessary because the operators are already 
initialized with the proper DAG
