Welcome to BP.net
I'm curious...why would you need to handle a snake that frequently?
Some of the hardier colubrids (such as a cornsnake) would probably be more tolerant of such handling. But they're not usually "lap snakes" either and are constantly moving so they need your undivided attention when you have them out. (Well, really, ANY snake should have your undivided attention while it's out...but some are at least more predictable in their movements.)
Anyhow...besides temperment issues....I'd also worry about temperature issues with some snakes. Ball pythons can get sick if exposed to cool temperatures for too long or too frequently or constantly fluctuating temps. (In and out of their enclosure every day) Most people keep their room temps far cooler than a ball python would find comfortable.....but cornsnakes can be kept at room temperature without risking illness.
