Black-headed python humidity question

Asking for a friend: they (and I) have done some searching and the only humidity requirements we can find in the sheets refers specifically to egg incubators rather than the animals actual living space. The only clues i could find indicate that it would be wetter than a woma, as it occupies a "semi-tropical" region of northern Australia which, as you can imagine, encompasses a whole range of climates. I'm inclined to assume 60's to 70's.(but its not my snake so i'm a bit nonchalant) Anyone have a specific best practice??

I don't do anything special for humidity and mine seem to be doing fine. Our indoor humidity is usually somewhere in the 40-60% range, depending on the season. I reckon you can bump that up a wee bit, considering they're kept in a box with a big bowl of water. I'm a fan of air exchange/flow so tend to start out with greater ventilation in exchange for less humidity. If an animal is showing signs of needing more - dehydration or bad sheds - then I'll work on raising the levels a bit.
