A future version of pandas will change to not sort by default. To accept the future behavior, pass 'sort=False'.

Parameters ---------- objs : list Series or DataFrame objects, may be mix of the two. intersect : bool, default False If True, calculate the intersection between indexes. Otherwise, calculate the union. axis : {0 or 'index', 1 or 'outer'}, default 0 The axis to extract indexes from. sort : bool, default True Whether the result index should come out sorted or not. copy : bool, default False If True, return a copy of the combined index.
