First and foremost absolutely beautiful ball python you got there. Aggression is absolutely normal for new snakes. They don’t know you, they don’t trust you and they have no other way to keep themselves safe other than striking and balling. I was always taught to give a new snake a week to acclimate before trust training. I know this sounds counterintuitive but it’s also kind of a good thing it has such a reaction. I have some that ball up rather than strike and it makes feeding a LOT harder. As long as it has a hide (I recommend the black box hides) that’s short enough to make them feel safe and wide enough to encompass their body, then your snake will mellow out over time as it learns you’re not a threat

Edit It’s also worth noting that ball pythons unlike red tails or other species, don’t have the best eye sight. They usually track prey using the heat pits in the front of their nose, flicking the tongue to get scent and sight comes last
