A groupby operation involves some combination of splitting the object, applying a function, and combining the results.

GroupBy.ngroup ( [ascending]) Number each group from 0 to the number of groups - 1. GroupBy.nth (n [, dropna]) Take the nth row from each group if n is an int, or a subset of rows if n is a list of ints. GroupBy.ohlc () Compute open, high, low and close values of a group, excluding missing values.

Group Series using a mapper or by a Series of columns. A groupby operation involves some combination of splitting the object, applying a function, and combining the results. This can be used to group large amounts of data and compute operations on these groups. Parameters. bymapping, function, label, or list of labels.
