|
Extract combined index: return intersection or union (depending on the
|
value of "intersect") of indexes on given axis, or None if all objects
|
lack indexes (e.g. they are numpy arrays).
|
|
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.
