Definition and Usage

The rpow() method raises a specified number with each value in the DataFrame.

This method is called reverse pow, and is similar to the pow() method, but instead of calculating 45 it calculates 54.

The specified number must be an object that can be used to raise the values in the DataFrame. It can be a constant number like the one in the example, or it can be a list-like object like a list [5, 10] or a tuple {"points": 5, "total": 10}, or a  Pandas Series or another DataFrame, that fits with the original DataFrame.


Syntax

dataframe.pow(other, axis, level, fill_value)
