thinking of getting a blood soon, but i have some questions

so january and february have been good money months serving, and i think i could be in a good spot to finally get a blood python (or maybe a sumatran depending on prices, i really just want a short tailed python im not picky)

for everyone who owns one:

1. what size enclosure do you have your snake in a how big is your snake? i know since short tails are ambush predators they arent as active as something like a ball python, thus they dont have as much of a space requirement (correct me if im wrong)

2. how much does your general upkeep cost? startup will always be pricey but the general maintenance is what matters

3. anything else i should consider that i may not have thought about?
