Bazooka blast ev3 Mindstorms using Python I would like to shoot balls with the ev3 Lego robot. How can I code it using Python?

Which components do I need for that and which function and motor use ?
ev3dev works pretty well for that purpose, and all you need is a microSD card.

You'll need to use the Motor class. It work with both large and medium motors, and either can be use to shoot balls, so this part will be at your preference.
