I was warned off Jungles, but it was the 1 python that suited my needs for space, size and colour. I wanted a fairly active arboreal python that didn't grow huge. For me, it was a toss up between a Jungle and a Diamond, but the more I looked at Jungles, the more I had to have one.
I was told by a few people "Don't get one, they're snappy" etc etc, but with patience, a calm confident approach and the utmost respect for their space, I find them amazing and once a python settles in (any python) the right approach is all you need. You will learn the signals when they are more reactive and when it's best to leave them be and you will be rewarded with an amazing family member for your kids too.
My boy came from a breeder on these forums (no longer breeds, shame, he had some amazing Jungles) and he is originally a Southern Cross Reptiles line. He was flighty and super fast when he was a hatchy and still now, if he is in "ima eat you" mode (branch hanging etc) he will headbutt the enclosure if I accidentally spook him .
I actually
LIKE the fact that someone just can't go in there, grab him and man-handle him - they will get tagged. I have only even been bitten once by him (Day 1 in fact) but as I respect his boundaries and am slow and steady when I handle him, he is a calm and non reactive snake.
Get what your instincts tell you to get - then research your breeders and go from there.
Best of luck
