People who have been coding for years will tell you that abstraction is always a good thing. It makes the system more robust and tolerant to future changes. Recently, I’ve been working on some Python libraries that wrap C extensions. While working on those libraries, a couple of interesting things came up.This blog post is about one of those things, and how it affects the speed. When we talk about abstraction, we tend to think about hierarchies, encapsulations, and robustness in general. But what about the ways in which they are implemented underneath? Different languages implement this in their own way, and they are not always optimal. This is what we are going to talk about. Let’s dive in, shall we?   Continue reading “The Cost Of Abstraction In Python” →
