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

             Summary: print() from python operators end up with extra new line
                 Key: AIRFLOW-1917
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-1917
             Project: Apache Airflow
          Issue Type: Bug
    Affects Versions: 1.9.0
            Reporter: Ash Berlin-Taylor
             Fix For: 1.9.1


If I have the following as the callable for a PythonOperator:

{code}
def print_stuff(ti, **kwargs):
    print("Hi from", __file__)
    print("Hi 2 from", __file__)
{code}

I see the following in the log files

{noformat}
