pandas.DataFrame.unstack¶
- DataFrame.unstack(level=-1)¶
Pivot a level of the (necessarily hierarchical) index labels, returning a DataFrame having a new level of column labels whose inner-most level consists of the pivoted index labels. If the index is not a MultiIndex, the output will be a Series (the analogue of stack when the columns are not a MultiIndex)
- level : int, string, or list of these, default last level
- Level(s) of index to unstack, can pass level name
>>> s one a 1. one b 2. two a 3. two b 4.
>>> s.unstack(level=-1) a b one 1. 2. two 3. 4.
>>> df = s.unstack(level=0) >>> df one two a 1. 2. b 3. 4.
>>> df.unstack() one a 1. b 3. two a 2. b 4.
