  • GroupBy

    Object that groups together rows of a dataframe based on the value of the passed column.

    <GB> = <DF>.groupby(col_key/s)                 # Splits DF into groups based on passed column.
     <DF> = <GB>.apply/filter(<func>)               # Filter drops a group if func returns False.
