Python molurus ranges across the lower half of the Asian continent. The species' western limit is thought to be the Indus Valley. It may range as far north as Quingchuan County of Sichuan Province, China, and as far south as Borneo. Indian pythons seem to be absent from the Malayan Peninsula. It has yet to be determined whether the populations scattered throughout several of the smaller islands are native or feral (escaped pets) populations. There are two recognized subspecies of P. molurus which are separated by geographic range and certain physical characteristics. P. molurus molurus is native to India, Pakistan, Sri Lanka, and Nepal. The larger of the two, P. molurus bivitatus (the Burmese python), is typically thought to range from Myanmar eastward across southern Asia through China and Indonesia. It is not present on the island of Sumatra. Introduced individuals have been sighted in the Florida Everglades.
