- DataFrame.applymap(func: Callable, na_action: str = None, skip_infer: bool = False, **kwds)#
Apply a function to a Dataframe elementwise.
Deprecated since version 2.1.0(pandas): DataFrame.applymap has been deprecated. Use DataFrame.map instead.
This method applies a function that accepts and returns a scalar to every element of a DataFrame.
- Parameters
func (callable) – Python function, returns a single value from a single value.
na_action ({None, 'ignore'}, default None) – If ‘ignore’, propagate NaN values, without passing them to func.
**kwargs – Additional keyword arguments to pass as keywords arguments to func.
- Returns
