Schedule a DAG via Python
You've learned quite a bit about creating DAGs, but now you would like to schedule a specific DAG on a specific day of the week at a certain time. You'd like the code include this information in case a colleague needs to reinstall the DAG to a different server.
The Airflow DAG object and the appropriate datetime methods have been imported for you.
