Return the maximum of the values over the requested axis.
If you want the index of the maximum, use idxmax. This is the equivalent of the numpy.ndarray method argmax.
Axis for the function to be applied on. For Series this parameter is unused and defaults to 0.
For DataFrames, specifying axis=None will apply the aggregation across both axes.
Added in version 2.0.0.
Exclude NA/null values when computing the result.
Include only float, int, boolean columns. Not implemented for Series.
Additional keyword arguments to be passed to the function.

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()
