To echo Connie on this one...
PLEASE do not acquire a blood python on impulse. While they aren't "rocket science" to keep, they do require attention from a dedicated herper with decent experience in successfully keeping snakes.
Not trying to be snarky, but if you have snakes getting loose, it may be time to brush up on your husbandry before tackling a species that requires more experience. Otherwise it may end up just being a bad experience for both you and the snake.
