Pythons are found in all tropical and temperate areas almost everywhere across the world. I think North America is the only place that does not really have an indigenous python species but I may be wrong. However, the USA particularly Florida has a huge influx of invasive Burmese pythons that are decimating local wildlife. So, like I say, no indigenous pythons.
All across Asia and Africa we have these constrictors both big and small. The reticulated python, the boa constrictor, the African and Indian rock pythons, the Burmese python and so on inhabit the wet and not so wet forests and jungles in the areas.
This video was shared with me by a guide in the Kruger Park. The snake was released into the wild by. a researcher and snake expert in Swaziland. It is a gravid (pregnant)female. Certainly the longest and biggest one i have ever seen.
