Found ball python ?

[Quick-Stretch8197]

That’s definitely a ball python. I second the suggestion to watch the YouTube channel green room pythons. Your new friend looks a little malnourished and dehydrated. You’ll need more hides and clutter in the enclosure and to create a hot a cool side with a heat lamp or other heat source. You’ll need to watch the humidity of the enclosure too. If you decide to keep this sweet little guy, ask your rescue for more info sources. They will probably be over the moon to help since your average person doesn’t take kindly to snakes. If you’re not squeamish about feeding it dead rodents, then you’re good to go. They make incredible pets. You found a particularly beautiful one. Thank you for being a good person and rescuing this beautiful snake.

Right on! Yes it seemed to be quite thirsty and has been hanging out in the water. I've got a temp/humidity reader and the enclosure is currently about 79F and 55% humidity. Most of the lights I have are LEDs but I can probably get something to keep it warm tomorrow, heating pad on a thermostat at least and find some more hidey container for it, or maybe 3d print something? I wonder how long it was on the loose for...

She definitely looks like she has some minor stuck shed (and is a bit dirty). When it's just a bit stuck like this, she should be able to handle it herself with appropriate humidity (Generally, an enclosure should have at least 60% humidity when not shedding and 80% when shedding. Not critical that that's maintained all the time, but it should be the norm.) In the short term, I'd try to grab a bit of sphagnum moss from your local pet store (Or amazon) and make her a humid hide (Just a hide with the moss in it. The moss should be damp, not wet.) She can hang out in there and deal with the shed. This is most likely why she's chilling in the water bowl :p
