I've always seen my snakes drink often. But mine were (and are) in display cages. The new ones will be once they are big enough for the display cages, as well.

The ball pythons I've had for years would even drink from the nozzle of the mister. I would let the water drip out and they drank.

My new Bumble Bee drank right after she arrived from shipping. She took a looooooong drink, too !!!
