This can make it easier to maintain and extend the existing code base. Update Feb 2024: you can also leverage… Continue reading Elevate Your Python: Harnessing the Power of Abstract Base Classes (ABCs)

Learning Python Decorators by Example
By Bob Belderbos on 20 October 2017
Decorators are a sometimes overlooked feature and they might be hard to grasp for beginning Pythonistas. I agree with Aaron Maxwell that mastering them “can massively magnify the positive impact of the code you write”, so make sure you add them to your toolkit if not done so already. In this article I explain what they do, why you want to use them and give some practical examples.
