Have had many, a king snake should be fine to start with, just remember when they shed they may strike at you because they can not see.
One thing on all pets, look what happen with the 14 yr old chimp attack the woman.
All can attack at sometime, more people have been bitten by dogs that DONT BITE. Danger is when that pet has the power to kill.
Pitbull can kill because of locking jaws, snake over 12 ft should never be handle unless more than one person is around.
Some of larger birds can kill(Ostrich).
Sorry little off the subject.
Rooster or king snake Either should be able to be handle by an adult when they are mad.
