pandas.DataFrame.rmul   DataFrame.rmul(other, axis='columns', level=None, fill_value=None)[source]
 
Get Multiplication of dataframe and other, element-wise (binary operator rmul). Equivalent to other * dataframe, but with support to substitute a fill_value for missing data in one of the inputs. With reverse version, mul. Among flexible wrappers (add, sub, mul, div, mod, pow) to arithmetic operators: +, -, *, /, //, %, **.  Parameters 
 
other:scalar, sequence, Series, 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.  
level:int or label


Broadcast across a level, matching Index values on the passed MultiIndex level.  
fill_value:float 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.      See also  DataFrame.add
