Why do we have to learn all these magic methods?

I do understand the usage of dunder init, as you tell the system what inputs to expect. But why do we have to know add, or str or radd or iadd?

Depending on the purpose of your class, you might not need all (or any) of those methods, but they will be important if you want to create objects that can be printed or that you can perform math on.
