Examples

>>> df = ps.DataFrame({"A": [1, 2, 1, 2], "B": [True, False, False, True],
...                    "C": [3, 4, 3, 4], "D": ["a", "a", "b", "a"]})
>>> df.groupby("A").min().sort_index()
       B  C  D
A
1  False  3  a
2  False  4  a

Include only float, int, boolean columns when set numeric_only True.

>>> df.groupby("A").min(numeric_only=True).sort_index()
       B  C
A
1  False  3
2  False  4

>>> df.groupby("D").min().sort_index()
   A      B  C
D
a  1  False  3
b  1  False  3

>>> df.groupby("D").min(min_count=3).sort_index()
     A      B    C
D
a  1.0  False  3.0
b  NaN   None  NaN
