F-strings with superpowers: What’s new in Python 3.14 beta

Are you ready for Python Pi? The 3.14 beta is out now, and we’ve got the rundown on what’s so great about it, including the new template strings feature, or “f-strings with superpowers.” You can also learn how to deploy Python (and other languages) to WebAssembly, get started with uv (the little Rust-powered Python tool that could), and take a one-year lookback at the free-threaded version of Python.
