Series.
unstack
Unstack, a.k.a. pivot, Series with MultiIndex to produce DataFrame. The level involved will automatically get sorted.
Level(s) to unstack, can pass level name.
Unstacked Series.
Notes
Unlike pandas, pandas-on-Spark doesn’t check whether an index is duplicated or not because the checking of duplicated index requires scanning whole data which can be quite expensive.
Examples
>>> s = ps.Series([1, 2, 3, 4], ... index=pd.MultiIndex.from_product([['one', 'two'], ... ['a', 'b']])) >>> s one a 1 b 2 two a 3 b 4 dtype: int64
>>> s.unstack(level=-1).sort_index() a b one 1 2 two 3 4
>>> s.unstack(level=0).sort_index() one two a 1 3 b 2 4
