pandas.Series.prod

Series.prod(self, axis=None, skipna=None, level=None, numeric_only=None, min_count=0, **kwargs)[source]

Return the product of the values for the requested axis.

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.

min_countint, 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 0. This means the sum of an all-NA or empty Series is 0, and the product of an all-NA or empty Series is 1.

**kwargs

Additional keyword arguments to be passed to the function.

Returns
scalar or Series (if level specified)
Examples
By default, the product of an empty or all-NA Series is 1
>>> pd.Series([]).prod()
    ..
1.0
This can be controlled with the min_count parameter
>>> pd.Series([]).prod(min_count=1)
    ..
nan
Thanks to the skipna parameter, min_count handles all-NA and
empty series identically.
>>> pd.Series([np.nan]).prod()
    ..
1.0
>>> pd.Series([np.nan]).prod(min_count=1)
    ..
nan
