Python 3.14’s beta release is now available, introducing several exciting features that can benefit developers. Key highlights include template strings, deferred-evaluated annotations, and improved error reporting.
Template strings have evolved to provide superpowers for formatting data. This new method transcends limitations of old-fashioned f-strings and offers a better way to handle data.
Python 3.14 also enables deployment to WebAssembly, allowing developers to run their apps on the web using this cutting-edge runtime. The Py-to-Wasm pipeline is still being built, but it’s essential for those interested in deploying Python apps.
A new package installer called uv has been introduced, offering a superfast way to track project dependencies, manage virtual environments, and stay organized with your Python projects.
The beta release also marks an important milestone: one year since the introduction of free-threaded Python. Quansight Labs uses this build in production and shares its experience in a manifesto for others who want to adopt it.
Additional resources include DumPy, a NumPy alternative for beginners, and Luciole Math, an easy-to-read typeface designed for academic users.
