pandas.DataFrame.rmod#

DataFrame.rmod(other, axis='columns', level=None, fill_value=None)[source]#

Get Modulo of dataframe and other, element-wise (binary operator rmod).

Equivalent to other % dataframe, but with support to substitute a fill_value for missing data in one of the inputs. With reverse version, mod.

Among flexible wrappers (add, sub, mul, div, floordiv, mod, pow) to arithmetic operators: +, -, *, /, //, %, **.

Parameters:
otherscalar, sequence, Series, dict or DataFrame

Any single or multiple element data structure, or list-like object.

axis{0 or ‘index’, 1 or ‘columns’}

Whether to compare by the index (0 or ‘index’) or columns. (1 or ‘columns’). For Series input, axis to match Series index on.

levelint or label

Broadcast across a level, matching Index values on the passed MultiIndex level.

fill_valuefloat or None, default None

Fill existing missing (NaN) values, and any new element needed for successful DataFrame alignment, with this value before computation. If data in both corresponding DataFrame locations is missing the result will be missing.

Returns:
DataFrame

Result of the arithmetic operation.

Examples

>>> df = pd.DataFrame({'angles': [0, 3, 4],
...                    'degrees': [360, 180, 360]},
...                   index=['circle', 'triangle', 'rectangle'])
>>> df
           angles  degrees
circle          0      360
triangle        3      180
rectangle       4      360

Calculate modulo with a scalar.

>>> 1000 % df
           angles  degrees
circle        NaN    280.0
triangle      1.0    100.0
rectangle     0.0    280.0

>>> df.rmod(1000)
           angles  degrees
circle        NaN    280.0
triangle      1.0    100.0
rectangle     0.0    280.0

Calculate modulo with a list.

>>> [1000, 2000] % df
           angles  degrees
circle        NaN    200.0
triangle      1.0     20.0
rectangle     0.0    200.0

>>> df.rmod([1000, 2000], axis='columns')
           angles  degrees
circle        NaN    200.0
triangle      1.0     20.0
rectangle     0.0    200.0
