FREE SNAKE!!!

so today i was working at petco and a guy comes in and we start a small convo on snakes. he tells me "if i want one more" and that he'll give me his 5-6 ft. carpet python(female?) for FREE!! im like OK!!!! he told me she has a nice temper and is eating well. so now i've added this beautiful carpet python to my snake keeping. so...any specific needs? temps?humidity? temper? in the mean time i'll do some research on it....will have pics of it soon!!! oh i hear she does a noise like a somewhat loud whistling sound,last like 2-3 seconds...RI?
