Cloudflare has made its Python Workers platform generally available, following a two-year preview period. Python is now a first-class, fully supported language on the Cloudflare Developer Platform. This advancement is made possible by running Python code in their server-side Workers platform as compiled WebAssembly using Pyodide.
However, this setup has some limitations, as multiprocessing and threading are not functional in the WebAssembly VM. Cloudflare's pywrangler development tool, available at PyPI as workers-py, simulates the entire stack locally, including executing Pyodide code in the WebAssembly runtime within a 123MB workerd binary. The development of Python Workers underscores Cloudflare's commitment to enhancing the Python ecosystem.
Gyeongjae Choi, Dominik Picheta, and Hood Chatham, both core Pyodide maintainers, are credited with the release.
