The mod() method finds the modulo (remainder) of each value in the DataFrame when you divide them by a a specified value.

The specified value must be an object that can be divided from 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 [15, 20] or a tuple {"points": 380, "total": 22}, or a  Pandas Series or another DataFrame, that fits with the original DataFrame.


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


Parameter Description

0 or 'index' means compare by index.
1 or 'columns' means compare by columns
level Optional. A number or label that indicates where to compare.
