From F# to Python with Fable
summary
Fable now compiles F# into Python source (Python 3.9 compliant) and runs its test suite for Python with about 1500 unit tests passing while JavaScript has ~2500; Python support is beta in Fable 4. It prints PEP8 code, emits type hints, maps F# async/task to Python async/await, and uses NuGet + Poetry with femto to sync deps. A Giraffe-style web layer is transpiled to an ASGI-compatible giraffe app and a SafeStack-style to‑do demo runs under uvicorn with working API calls.
