Type Annotations with Larger Codebases

Explore advanced techniques for implementing type annotations in large-scale Python projects in this 30-minute EuroPython 2018 conference talk. Delve into real-world challenges and best practices for integrating type annotations into existing codebases with tens or hundreds of thousands of lines of code. Learn strategies for encouraging team-wide adoption, overcoming common obstacles, and maximizing the benefits of type annotations. Discover how to work effectively with non-annotated third-party libraries, address code patterns that may not align well with annotations, and identify scenarios where refactoring is necessary for proper type checking. Gain valuable insights from Yelp's experience in implementing type annotations across their extensive codebase, equipping you with practical knowledge to enhance code quality, reduce bugs, and improve documentation in large Python projects.
