Use zero initialization for the … TīmeklisThis method passes each column or row of your DataFrame one-at-a-time or the entire table at once, depending on the axis keyword argument. For columnwise use axis=0, rowwise use axis=1, and for the entire table at once use axis=None. This method is powerful for applying multiple, complex logic to data cells.
