## Health v2 (maintenance only)
Score: 77/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 99, release rhythm 35, longevity 100
- inputs: {"age_days": 3491, "days_push": 7, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases, no_license
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
CPython is the reference implementation of the Python programming language, containing the interpreter, compiler, and standard library. It is maintained by the Python Software Foundation and is the canonical runtime that defines Python's behavior.

## Use cases
- run python scripts
- install the python interpreter
- learn python programming
- build python from source
- contribute to python core development
- embed python in a c application
- test code against the latest python version

## When to choose
- you need the official, canonical Python runtime
- you want to test compatibility with upcoming Python releases
- you want to contribute to Python itself or its standard library
- you need to embed a Python interpreter via the C API

## When to avoid
- you need maximum performance for CPU-bound work (consider PyPy or native code)
- you want an alternative runtime like PyPy, MicroPython, or Jython
- you only need to install Python for end use - prebuilt installers from python.org are simpler
