Axis for the function to be applied on. skipnabool, default TrueExclude NA/null values when computing the result. levelint or level name, default NoneIf the axis is a MultiIndex (hierarchical), count along a particular level, collapsing into a scalar. numeric_onlybool, default NoneInclude only float, int, boolean columns. If None, will attempt to use everything, then use only numeric data. Not implemented for Series. min_countint, default 0The required number of valid values to perform the operation. If fewer than Additional keyword arguments to be passed to the function. Returnsscalar 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 By default, the sum of an empty or all-NA Series is >>> pd.Series([], dtype="float64").sum() # min_count=0 is the default 0.0 This can be controlled with the >>> pd.Series([], dtype="float64").sum(min_count=1) nan Thanks to the >>> pd.Series([np.nan]).sum() 0.0 >>> pd.Series([np.nan]).sum(min_count=1) nan View Discussion Improve Article Save Article View Discussion Improve Article Save Article Python is a great language for doing data analysis, primarily because of the fantastic ecosystem of data-centric python packages.
