PandasdrillGroup means as a flat table
A pandas exercise from Pandasdrill. Solve it with a Python editor in your browser running real pandas, and it is checked the moment you submit.
The task
Return the average `units` per product as a DataFrame with two columns, `product` and `units`, and a plain 0, 1, 2 index.
What this exercise teaches
By default the group keys move into the index and a single column comes back as a Series. as_index=False, or reset_index(), turns the result back into an ordinary table with product as a column.
A hint if you get stuck
as_index=False keeps the group key as a regular column. reset_index() after the fact does the same.
