Great Tutor,
i got some error like in process_iris_data like
data=iris[0],
IndexError: list index out of range
could you help me where i go wrong?

All your videos are really great, and helped me understand Apache Airflow much better! However now I find that you copy-paste your code (vis-a-vis your previous two videos). Maybe for future reference, people learning new things really prefer to have code typed as one can match the speed.
