Carpet pythons get some size on them, particularly the coastal subspecies, with jungles being a bit smaller than the coastals. Depending on sex, subspecies makeup, and general parentage, jungles, coastals, and jungle/coastal crosses will generally max out in the 7-10ft range. On some occasions, big older female coastals will break 10 foot, but I wouldn't personally let that double-digit number scare you.

Look up carpet pythons on youtube to find good examples of adults in relation to human size and you should see that they get some respectable size while still being quite managable being handled by one average sized person.
