Score: 77/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 99, release rhythm 35, longevity 100
- inputs: {"age_days": 4712, "days_push": 9, "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
The canonical repository of Python Enhancement Proposals (PEPs), the design documents and standards that govern Python's development, published automatically at peps.python.org. It contains PEP sources in reStructuredText, build tooling to render them to HTML, and a JSON API of PEP metadata.

## Use cases
- read the official Python style guide PEP 8
- look up how a Python language feature was proposed and accepted
- find the process for proposing a change to Python
- check the status of packaging or typing standards
- render PEPs locally to preview a new proposal
- fetch PEP metadata programmatically via the JSON API

## When to choose
- you need authoritative Python language or packaging standards
- you want to draft or review a new PEP
- you need historical records of Python design decisions
- you want programmatic access to PEP metadata

## When to avoid
- you need executable code or a library to install
- you want general Python tutorials rather than specifications
- you need documentation for a specific Python module instead of language-level proposals

## Facets
- artifact type: dataset
- maturity: active
- function: documentation, markdown
- domain: programming-languages, documentation, developer-tools
- platform: python
- tags: peps, python-enhancement-proposals, specifications, restructuredtext, standards, governance, python-language, web-server
