Thank you for asking how to regulate the heat pad instead of posting pictures of Blackened Python.

You should definitely get the whole thing set up and monitor it for at least a few days to make sure it's consistent before you get the snake.

What kind of enclosure will you use? There's a great stickied guide on 'converting' aquariums to be snake friendly if that's the route you choose. They aren't ideal for heat, humidity, and security without a few mods. GL!
