# pandas.core.groupby.GroupBy.nth¶

Take the nth row from each group if n is an int, or a subset of rows if n is a list of ints.

If dropna, will take the nth non-null row, dropna is either ‘all’ or ‘any’; this is equivalent to calling dropna(how=dropna) before the groupby.

- param n
- int or list of ints
a single nth value for the row or a list of nth values

- param dropna
- None or str, optional
apply the specified dropna operation before counting which row is the nth row. Needs to be None, ‘any’ or ‘all’

- return
Series or DataFrame N-th value within each group.
