Abstract

Before releasing the chaos, we will explore how the "ast" module can programmatically analyze and manipulate Python code at an abstract syntax level and how this abstract syntax tree concept helps existing tools like Black improve the Python world. Once we know the secret, we will guide you in building a custom linter using this module. This technique is particularly useful when configuring existing tools that cannot fix your style problems or if you want to make your Python code unpythonic. Join us to learn more and bring chaos to the Python world!
