Yes! Cornsnakes are low maintenance but can be handled. Most of us use heat mats (under tank heaters) and they stay on 24/7 but use about 4W of power (compare to 50-150W for an incandescent light bulb) so are cheap to operate. Babies are fed every 5 days, subadults and adults every 7-14 depending. They eat appropriately sized frozen/thawed mice. Substrate can be aspen shavings, papertowels, newspaper. Cleaning depends on the substrate. If it's aspen, spot clean when you see poop, dump & replace monthly if it is a small enclosure like a 6Q rubbermaid for a baby, dump and replace every 2 months for big enclosures like a 20G aquarium for an adult. Water dish is anything cheap the snake can't tip over. Many people like dog water bowls for bigger snakes. I use anything handy, like soup bowls from Walmart ($1 each) for adults, and little tiny cups meant for condiments for babies (4/$1 at Walmart). Water should be dumped & replaced every couple days, and I clean out water bowls, rather than dump & refill, once a week, because water bowls always get slimy. If they poop in their water bowl it will need cleaning sooner. So basically you have to attend to their physical needs about 2x weekly, and handle in between. The cleaning part takes 5 minutes. Feeding takes longer but most of that is thawing the food item, and while it is thawing in warm water you can do something else, then run really hot tap water on it, let it sit 2 minutes and serve!
They are the easiest pet I've ever kept. I have had cats, dogs, mice, hamsters, gerbils, and LOTS of tropical fish.
Edit: they don't need special humidity. If it's not too humid or too dry for you, it's probably fine for corn snakes. They don't need the cool side of their enclosure heated. They need a warm side at about 84F, and the cool side is fine at a temperature that you consider comfortable for shirtsleeves, like 70-75F. Mine even seemed fine with the 68F in my apartment over the winter. They don't need special UV lamps. They don't even need as much or as full-spectrum of lamps as keeping aquarium fish requires. They don't need a lamp at all for their health if they live in a room that gets indirect natural light, the only lights you might want are so you can see your snake.
I couldn't possibly have so many (see my sig) if they weren't easy care!
