How do you verify and validate the data coming into your Python web application? What tools and security best practices should you consider as a developer? Christopher Trudeau is back on the show this week, bringing another batch of PyCoder's Weekly articles and projects. 👉 Links from the show: https://realpython.com/podcasts/rpp/202/ We discuss the recent Real Python tutorial "Pydantic: Simplifying Data Validation in Python." The piece covers installing the library with optional dependencies, working with base models, validating functions, and managing environment variables. We continue our conversation about web development with another article about Python security best practices. This article covers several Python libraries and crucial steps you can take to help make your web-based applications more secure. We also share several other articles and projects from the Python community, including a news roundup, why Python lists multiply oddly, inline run dependencies in pipx, a discussion about open-source contribution assignments, playing sounds in Python, and a Python library to access ISO country definitions.
