Examples

For SeriesGroupBy:

>>> lst = ['a', 'a', 'b']
>>> ser = pd.Series([1, 2, 0], index=lst)
>>> ser  
a    1
a    2
b    0
dtype: int64
>>> ser.groupby(level=0).any()  
a     True
b    False
dtype: bool

Copy

For DataFrameGroupBy:

>>> data = [[1, 0, 3], [1, 0, 6], [7, 1, 9]]
>>> df = pd.DataFrame(data, columns=["a", "b", "c"],
...                   index=["ostrich", "penguin", "parrot"])
>>> df  
         a  b  c
ostrich  1  0  3
penguin  1  0  6
parrot   7  1  9
>>> df.groupby(by=["a"]).any()  
       b      c
a
1  False   True
7   True   True
