Well just keep in mind that ball python's aren't demesticated to the point that dogs and cats are, for the most part they are still wild animals (many are wild caught) if you accidentally did something to corner her or threaten her otherwise (that you may not have realized) she may be inclined to defend herself.
Just remember they have teeth and use them from time to time. WHen i got my first snake my dad said, you'll eventually get bit, you still want it? So just remember this may be the first but quite possibly won't be the last!
good luck, take pics next time!
