Jungle carpet python or iguana?

ok this is one of the biggest things ive ever had to decide on since im an animal lover. 1 day i just decided to buy a jungle carpet python (JCP) so i come home with the snake my mom freaks but in the end i keep the snake. but as soon as i brought it home i relaized itwas a nasty mother ****** but i still tried taming it down down but winding yup with 15 bite marks and no progress in the end. but yet i never gave up. but my mom is always killin me about the snake and its geting annoying now today my mom says if u sell ur snake i will buy u any lizard u want and buy u a 60galon breeder tank with it. i always wanted an iguana but i have come so attached to my JCP that i cant bear to sell it. even though i get bit that thing daily i still for some reaso love it i need u guys to decide for me
