pandas.Series.max

Series.max(axis=None, skipna=None, level=None, numeric_only=None, **kwargs)

Return the maximum of the values over the requested axis.

If you want the index of the maximum, use idxmax. This isthe equivalent of the numpy.ndarray method argmax.

Parameters

axis{index (0)}

Axis for the function to be applied on.

skipnabool, default True

Exclude NA/null values when computing the result.

levelint or level name, default None

If the axis is a MultiIndex (hierarchical), count along a particular level, collapsing into a scalar.

numeric_onlybool, default None

Include only float, int, boolean columns. If None, will attempt to use everything, then use only numeric data. Not implemented for Series.

**kwargs

Additional keyword arguments to be passed to the function.

Returns

scalar or Series (if level specified)

Examples

>>> idx = pd.MultiIndex.from_arrays([
...     ['warm', 'warm', 'cold', 'cold'],
...     ['dog', 'falcon', 'fish', 'spider']],
...     names=['blooded', 'animal'])
>>> s = pd.Series([4, 2, 0, 8], name='legs', index=idx)
>>> s
blooded  animal
warm     dog       4
         falcon    2
cold     fish      0
         spider    8
Name: legs, dtype: int64

>>> s.max()
8

Max using level names, as well as indices.

>>> s.max(level='blooded')
blooded
warm    4
cold    8
Name: legs, dtype: int64

>>> s.max(level=0)
blooded
warm    4
cold    8
Name: legs, dtype: int64
