Python Pitfalls: Common Mistakes and How to Avoid Them | Real Python Podcast #315
What are common mistakes that Python beginners make, and how do you avoid them? 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/315/ We dig into an article about common pitfalls and mistakes new Python developers make. Some of the mistakes are due to Python doing exactly what you asked it to do. We also talk about Real Python resources for getting started with the language and building your development environment. We also share other articles and projects from the Python community, including recent releases, a collection of new PEPs, the results of two recent Python elections, creating temporary files in Python, decoupling pure logic from Django's ORM, a Python functions reference, a lightning-fast logger, and an online development environment for creating games.
