Managing Polars Schemas Issues & Profiling GitHub Users | Real Python Podcast #296

How can you avoid schema problems in your Polars data pipeline when adding new columns? How can you quickly examine a GitHub user's profile to decide how much to invest in their contributions? Christopher Trudeau is back on the show this week with another batch of PyCoder's Weekly articles and projects. 👉 Links from the show: https://realpython.com/podcasts/rpp/296/ Christopher shares a recent article about handling schema issues in Python Polars. The piece covers ways that a schema change can break your data pipeline. It provides strategies to avoid and resolve issues. We cover a recent project from previous guest Eric Matthes to investigate GitHub profiles of a potential contributor. With the rise of AI-slop pull requests, the tool can provide valuable background on the user. We also share other articles and projects from the Python community, including recent releases, exploring four different "get" special methods, what's new in Pip 26.1, inverse Sapir-Whorf and programming languages, and a Python scripting framework for CAD.
