From 'Barely Works' to Pythonic Code in 5 steps

In this video, we adapt a clumsy, non-Pythonic API into an easy to use, easy to understand Pythonic one. We use magic methods such as getitem_, len, enter, and _exit to make our objects a context manager and support the len() function and square bracket indexing. And in the end, we turn what once was ugly, difficult to maintain code into something that other developers would actually want to use.
