Parameters:

Name	Description	Type/Default Value	Required / Optional
other	Any single or multiple element data structure, or list-like object.	scalar, sequence, Series, or DataFrame	Required
axis	Whether to compare by the index (0 or ‘index’) or columns (1 or ‘columns’). For Series input, axis to match Series index on.	{0 or ‘index’, 1 or ‘columns’}	Required
level	Broadcast across a level, matching Index values on the passed MultiIndex level.	int or label	Required
fill_value	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.	float or None Default Value: None	Required
