[AIRFLOW-882] Remove unnecessary dag>>op assignment in docs
Closes #2088 from dhuang/AIRFLOW-882
> 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
> Fix For: 1.8.1
>
>
> 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 (https://github.com/apache/incubator-airflow/blob/fb0c5775cda4f84c07d8d5c0e6277fc387c172e6/airflow/models.py#L1699).
