Using a DataFrame
In the previous exercise, you saw how to split up a task and use the low-level python multiprocessing.Pool API to do calculations on several processing units.
It's essential to understand this on a lower level, but in reality, you'll never use this kind of APIs. A more convenient way to parallelize an apply over several groups is using the dask framework and its abstraction of the pandas DataFrame, for example.
The pandas DataFrame, athlete_events, is available in your workspace.
