Feeling bad and or stressing about a situation does not make it better. There is tons of good information on this forum. Take some time, read it, and share it with your father. Ball pythons are not hard or expensive to take care of, but their behaviors are way different than the snakes you said your father kept.
BTW you are not stupid. You are looking for an answer. Not knowing is not stupid. Generally the people that think they know everything are the stupid ones. Smart people know when they don't know.
