pandas.DataFrame.sem

DataFrame.sem(axis=None, skipna=None, level=None, ddof=1, numeric_only=None, **kwargs)

Return unbiased standard error of the mean over requested axis.

Normalized by N-1 by default. This can be changed using the ddof argument

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