Panel.product(axis=None, skipna=None, level=None, numeric_only=None, min_count=0, **kwargs)[source]

Return the product of the values for the requested axis


axis : {items (0), major_axis (1), minor_axis (2)}

skipna : boolean, default True

Exclude NA/null values when computing the result.

level : int or level name, default None

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

numeric_only : boolean, default None

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

min_count : int, default 0

The required number of valid values to perform the operation. If fewer than min_count non-NA values are present the result will be NA.

New in version 0.22.0: Added with the default being 1. This means the sum or product of an all-NA or empty series is NaN.


prod : DataFrame or Panel (if level specified)


By default, the product of an empty or all-NA Series is 1

>>> pd.Series([]).prod()

This can be controlled with the min_count parameter

>>> pd.Series([]).prod(min_count=1)

Thanks to the skipna parameter, min_count handles all-NA and empty series identically.

>>> pd.Series([np.nan]).prod()
>>> pd.Series([np.nan]).sum(min_count=1)
