I've never kept a carpet python before.
However, I do have a boa constrictor, a blood python, two Burmese pythons, an Amazon tree boa, 5 ball ball pythons, a milk snake, and a Selayar reticulated python.
Ball pythons aside, the only two I have that seem to be docile as all gives are the boa constrictor and the retic. The retic seems to enjoy it's time out - not making mad dashes (unless you pull her tail) but will actively explore and try to climb objects such as furniture. Oddly enough, she also tends to actually follow me around when placed on flat ground, seemingly trying to reach for my leg and climb it. Was a difficult eater the first few months I had her, but the stereotypical retic feeding response eventually kicked in.
My boa is pretty much like a lazy cat. Sometimes moves around, sometimes content to lie on your lap for hours on end or fall asleep somewhere like on the bed or couch. Also a little piggy.
For those of you with retics, are carpets essentially like retics in behavior? How do they differ?
