Python Enhancement Proposals
The PEPs in this repo are published automatically on the web at https://peps.python.org/. To learn more about the purpose of PEPs and how to go about writing one, please start reading at PEP 1. Note that the PEP Index (PEP 0) is automatically generated based on the metadata headers in other PEPs.

Checking PEP formatting and rendering
Please don't commit changes with reStructuredText syntax errors that cause PEP generation to fail, or result in major rendering defects relative to what you intend.
Browse the ReadTheDocs preview
For every PR, we automatically create a preview of the rendered PEPs using ReadTheDocs. You can find it in the merge box at the bottom of the PR page:
- Click "Show all checks" to expand the checks section
- Find the line for
docs/readthedocs.org:pep-previews - Click on "Details" to the right
Render PEPs locally
See the build documentation for full instructions on how to render PEPs locally. In summary, run the following in a fresh, activated virtual environment:
# Install requirements
python -m pip install -U -r requirements.txt
# Render the PEPs
make render
# Or, if you don't have 'make':
python build.pyThe output HTML is found under the build directory.
Check and lint PEPs
You can check for and fix common linting and spelling issues, either on-demand or automatically as you commit, with our pre-commit suite. See the Contributing Guide for details.
