Refactoring Large Programs [PyCon DE & PyData Berlin 2024]

🔊 Recorded at PyCon DE & PyData Berlin 2024, 22.04.2024 https://2024.pycon.de/program/CMM8S3/ 🎓 Watch Dr. Kristian Rother guide you through refactoring a large, messy, and undocumented Python program, offering valuable insights and strategies for your next big refactoring challenge. Speakers: Dr. Kristian Rother Description: Dr. Kristian Rother, a freelance Python trainer, presented a tutorial on refactoring large programs at a recent event. He addressed the challenge of cleaning up complex software with 10,000-100,000 lines of code, particularly in the case of legacy code. The tutorial focused on practical procedures such as code review, writing minimal tests, adding type annotations, and isolating cleanable parts from problematic sections. Dr. Rother emphasized the systematic approach to large-scale refactoring, highlighting that while it is difficult and costly, it can be tackled methodically. The session, aimed at those with fluency in basic Python, included interactive elements and practical exercises for attendees to enhance their refactoring skills. Participants were provided with the messy code and refactoring guidelines through GitHub for hands-on learning. ⭐️ About PyCon DE & PyData Berlin: The PyCon DE & PyData conference unite the Python, AI, and data science communities, offering a unique platform for collaboration and innovation.
