pandas.DataFrame.prod

Return the product of the values for the requested axis.

param axis

{index (0), columns (1)}

Axis for the function to be applied on.

param skipna

bool, default True

Exclude NA/null values when computing the result.

param level

int or level name, default None

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

param numeric_only

bool, default None

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

param 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 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.

return

Series or DataFrame (if level specified)

Limitations

Parameters axis, level, numeric_only and min_count are unsupported.

Examples

Return the product of the values for the columns.
