There is a huge difference in price and care between a GTP and a corn...
I would definitely not say a GTP is a beginner snake.
Get something simple, corn, ball, Red tail, king snake, milk snake... Hell my best recommendation would be a Hognose snake...
Ball Pythons being my second.
GTPs are not very well known to be hand friendly, and require an arboreal set up... If you do not mind getting bit/not holding your snake go ahead and get a GTP but do a fair bit of research and save yourself time and money by possibly losing that snake in the future do to lack of knowledge... It is not as simple as put it in a box and leave it, thats a ball python LOL
seriously though
put a ball python in a rubbermaid/sterilite tub with a UTH on a t-stat with a waterdish and a hide...
instant pet rock.
