Syntax Trees and Python - Automated Code Transformations
Joe Gordon at PyCon 2019
Manually updating a million line code base is tedious. Thankfully syntax trees provide a safe and quick way to automatically apply repetitive transformations. Leveraging syntax tree based tooling (based on lib2to3), has been a critical component of Pinterest's Python 3 upgrade strategy, and saved us countless hours of work. Learn how syntax trees work, how they are used to transform code, and how you can quickly write your own transformations.
