Cloudflare Python Workers are now generally available

Cloudflare has made Python Workers generally available after a two-year preview, calling Python a first-class language on its Developer Platform. Code runs as Python compiled to WebAssembly via Pyodide inside the V8-based workerd runtime, with threading and multiprocessing unsupported.

• Python is now a fully supported language on Cloudflare Developer Platform
• Code runs via Pyodide in WebAssembly inside the V8-based workerd runtime
• Threading and multiprocessing do not work in the WebAssembly VM
• The pywrangler tool simulates the stack locally in a 123MB workerd binary
