Yes! OOP is an amazing software design concept. I mean, I do see a change in even simple Excel VBA macros I write. Earlier, my code used to be monolithic and used a lot of loops. Now, its a lot cleaner, VBA doesnt have real OOP but does have basic classes and inheritance and I am making use of it!" Especially, the part on OOP, is so important as you learn to make your code modular and can apply it in any use case."
It's good to see that OO design and OOP is appreciated. Writing flexible and maintainable software is so important in real life.
Additionally, completing this course has really helped me learn Python much faster.
