pandas.DataFrame.floordiv#

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

Get Integer division of dataframe and other, element-wise (binary operator floordiv).

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

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_valuescalar or None, default None

Fill NA values, whether present in the original data or introduced by alignment, with this value before computation. Positions where both inputs are NA are left unfilled and behave as NA does for the operation.

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

Divide by a scalar.

>>> df // 2
           angles  degrees
circle          0      180
triangle        1       90
rectangle       2      180

>>> df.floordiv(2)
           angles  degrees
circle          0      180
triangle        1       90
rectangle       2      180

Divide by a list and Series.

>>> df // [1, 2]
           angles  degrees
circle          0      180
triangle        3       90
rectangle       4      180

>>> df.floordiv([1, 2], axis='columns')
           angles  degrees
circle          0      180
triangle        3       90
rectangle       4      180
