How big is she?
If they are together, they are very uncomfortable, usually seen with one on top of the other dominating each other. Despite contrary belief, ball pythons should never ever be kept in the same enclosure.
Even if she bred, you wouldn't get babies because you would probably not know how to incubate them.
Chances are she's too small to breed, and she could die in the process from being egg bound.

Get them in two different enclosures, pronto. Your risking illness, two vet bills, cannibalism, fighting, domination, and not eating. Not worth it.
