Het Pied and Het for Pied are the same thing really. A het pied looks like a normal ball python, If you wanted a pastel or some other snake that has the pied gene a lot of people say it's a pastel het for pied. It's just the way it's worded. One warning, if you do get Het pieds make SURE it's from a reputable breeder. You really can't tell a normal from a het. There are a few markers to look for but none of them are 100%. Personally I went with visual pied. I know it cost me more to start out but i also know 100% they are pieds.
