Goodbye to Flake8 and PyLint: faster linting with Ruff

Flake8 and PyLint are commonly used, and very useful, linting tools: they can help you find potential bugs and other problems with your code, aka “lints”. But they can also be slow. And even if they’re fast on your computer, they may still be slow in your CI system (GitHub Actions, GitLab, or whatever else.)

Happily, there’s a new linter available, Ruff, which is much faster. And it supports many of the same lints, including those from many of Flake8’s plugins.

In this article we’ll get a sense of why Ruff’s extra linting speed is so useful compared to the alternatives.

Python's Missing Batteries

Python is known to come with "batteries included", thanks to its very extensive standard library, which includes many modules and functions that you would not expect to be there. However, there are many more "essential" Python libraries out there that you should know about and be using in all of your Python projects, and here's the list.

Error handling patterns

Error handling is a fundamental aspect of programming. Unless you are writing “hello world”, you will need to handle errors in your code. In this post, I will discuss a bit the most common approaches used by various programming languages.
