I was talking about Python specifically. And no, of course it's not a silver bullet. It's a solution for structuring your code base in a way that lets you not lose track of what does what.

OOP not just inheritance. Object oriented programming starts with structuring things in objects, like the name suggests. It quickly has a place in anything more then a few hundred lines of code.

I rarely use inheritance. Like i said, I see OOP mainly as a way to achieve cleaner code structure and better readability. That last point is really my main concern.
