What type of carpet is he?

[DennisM]

Looks like a darwin carpet python (Morelia Spilota Variegat​a). They're more often seen in their Albino form.

He's beautiful by the way!

possibly, but I think it's far more likely an Irian Jaya, m.s.harissoni, if the OP is in the U.S. (I don't know OP's location) Darwins are still somewhat uncommon in the U.S. and most have been out crossed to other m.s.ssp in an attempt to accelerate the albino project. I doubt they've hit the chain stores here yet.
