Why setattr

I understand you can use setattr to accept unknown attributes but can someone give me real life examples of this in practice? I need the why behind the why! What kind of projects would benefit from this? A few ideas would help out greatly, thank you!

Let's say you want to create a class Car. You can add parameters like self, color, numb_of_seats, numb_of_doors and these need to be filled when creating an instance of Car. Later on, someone wants to create an instance of Car which has 3 engines (numb_of_engine = 3) and 8 wheels (number_of_wheels = 8) (not a car anymore). These parameters weren't provided before so that's how we can add them later, without changing the code. And there can be an unknown number of these parameters, with all kinds of names.

I'm also new to this and that's how I understood it. Hope it helps
