And the dead giveaway between a Rock and Burmese Python is a Rock Python does not have a prehensile tail.

I think any snake given the chance can learn trust and eventually calm down. I cautiously use the word tame when describing behavior of nondomesticated animals. Use plenty of protection and utilize a buddy system in case you need it and see what happens. I know I'm comparing apples to oranges here but I have successfully calmed wild caught full grown Bull snakes several times over the years but I did take a few licks in the process. Good luck.
