bigframes.pandas.DataFrame.rsub#

DataFrame.rsub(other: float | int | Series | DataFrame, axis: str | int = 'columns') → DataFrame[source]#

Get subtraction of DataFrame and other, element-wise (binary operator -).

Equivalent to other - dataframe. With reverse version, sub.

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

Note

Mismatched indices will be unioned together.

Examples:

>>> df = bpd.DataFrame({
...     'A': [1, 2, 3],
...     'B': [4, 5, 6],
...     })
>>> df['A'].rsub(df['B'])
0    3
1    3
2    3
dtype: Int64

It’s equivalent to using arithmetic operator: -:

>>> df['B'] - (df['A'])
0    3
1    3
2    3
dtype: Int64

Parameters:

other (float, int, or Series) – 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.

Returns:

DataFrame result of the arithmetic operation.

Return type:

bigframes.pandas.DataFrame
