FYI, I've kept a spotted python (Antaresia maculosa) for about 10 years now, she is NOT "terrestrial". She spends a lot of time on her branches, basking & hanging
out. You'd be missing the fun of keeping one of these without cage height & full visibility & she is not shy either...she is quick to investigate my presence even if she
is in one of her hides. (she is sensitive to floor vibrations, I assume) If you want one of these, I'd use a bigger enclosure, & glass tanks (kept warm!) work just fine.
Maybe one of the small milk snakes or hognose would work ok though.
