kurtqq commented on issue #5449: [AIRFLOW-4828] Remove parameter python_version URL: https://github.com/apache/airflow/pull/5449#issuecomment-504115895 I don't think we should remove `python_version `parameter. If I run Airflow on Python 3.5 and want to run a task with Python 3.7 I need the `python_version `parameter. Moreover in the future Python 4 will be released. Airflow will likely support both for a while.... I think the `python_version `needs to stay it's not unique to Python 2.7 I also think that if someone wants to run something with Python 2.7 with the `PythonVirtualenvOperator `he is more than welcome. There is no need to prevent the user from doing so. Airflow can just remove the test for this so if something is not working it's the user problem.
