| PythonOperator |
| ============== |
| |
| Use the :class:`~airflow.operators.python_operator.PythonOperator` to execute |
| Python callables. |
| |
| .. exampleinclude:: ../../../airflow/example_dags/example_python_operator.py |
| :language: python |
| :start-after: [START howto_operator_python] |
| :end-before: [END howto_operator_python] |
| |
| Passing in arguments |
| ^^^^^^^^^^^^^^^^^^^^ |
| |
| Use the ``op_args`` and ``op_kwargs`` arguments to pass additional arguments |
| to the Python callable. |
| |
| .. exampleinclude:: ../../../airflow/example_dags/example_python_operator.py |
| :language: python |
| :start-after: [START howto_operator_python_kwargs] |
| :end-before: [END howto_operator_python_kwargs] |
| |
| Templating |
| ^^^^^^^^^^ |
| |
| When you set the ``provide_context`` argument to ``True``, Airflow passes in |
| an additional set of keyword arguments: one for each of the :doc:`Jinja |
| template variables <../../macros-ref>` and a ``templates_dict`` argument. |
| |
| The ``templates_dict`` argument is templated, so each value in the dictionary |
| is evaluated as a :ref:`Jinja template <jinja-templating>`. |
