This post announces the General Availability (GA) of Python Workers, a significant evolution of the Cloudflare Workers platform. Key contributions include: 1. Native support for Cloudflare bindings, eliminating the need for explicit JavaScript glue code for RPC boundaries. 2. Implementation of WSGI/ASGI connectors (`workers.asgi`, `workers.wsgi`) to seamlessly run Python web frameworks (FastAPI, Django, Flask) on the Workers platform. 3. A socket system call implementation using the Workers `connect` API, enabling Python database drivers to connect to services like Hyperdrive (PostgreSQL/MySQL). 4. Standardization of a platform for running Python in browser runtimes via PEP 783 and PyEmscripten, benefiting the broader Python-on-WebAssembly community. 5. Stabilization of the Pyodide build toolchain and integration with `cibuildwheel` for easier package creation.
