PYPY
Fast tracing-JIT implementation of Python
MIT
ABOUT
CPython is slow on tight pure-Python loops that show up in simulators, agents, and numeric prototypes. PyPy traces those loops to machine code so teams keep Python source while cutting runtime, as long as the workload is not dominated by CPython C extensions.
INTEGRATION GUIDE
1. Speed up a pure-Python simulator or agent loop without Cython
2. Run a CPython-compatible interpreter with a tracing JIT
3. Prototype numeric code in Python before dropping to C
4. Replace CPython for long-running workers that stay in Python
