I have data (labeled as `df`) that looks like this(below) where the 'DATE' column is formatted as such -> MM/DD/YYYY.

I then need to group the available accident data by month.

Anyone know how to do this by first converting 'DATE' column to a `datetime` type, setting the index using `set_index` and then using `groupby` to group by month?
