Python 3.15: Exploring the New Features | Real Python Podcast #313
Python 3.15 is (almost*) here! Christopher Trudeau and Bartosz Zaczyński return to discuss the new version. Bartosz coordinated the series of preview articles with members of the Real Python team and wrote the showcase tutorial, "Python 3.15: Cool New Features for You to Try." Christopher's video course "What's New in Python 3.15" covers the topics from the article and shows the new features in action. 👉 Links from the show: https://realpython.com/podcasts/rpp/313/ Christopher and Bartosz dug into the release to create code examples of the new features for the tutorial and course. We cover the new built-in types, unpacking in comprehensions, and developer experience enhancements. We also look into the performance improvements, including lazy imports, the upgraded JIT compiler, and a new sampling profiler. We share our thoughts on the updates and offer advice about incorporating them into your projects. We also discuss when you should start running Python 3.15.
