An early stage PEP that introduces tag strings - a natural extension of "f-strings" from PEP 498 which enables Python developers to create and use their own custom tags (or prefixes) when working with string literals and any interpolation. Tag strings are based on a related idea in JavaScript, tagged template literals but with a Pythonic syntax for both the use of and the definition of tags.

This repository supports GitHub Codespaces.
With a single click, you can spin up a full browser-based development environment using vscode, and backed by a running container image with all the necessary development tools. No local installation is necessary, but you do need a GitHub account.
- Click the "Code" button on the home page for this repo
- Click the "Codespaces" tab
- Click "Create codespace on main"
- After things spin up, you'll have vscode in your browser, attached to cloud dev environment
- Open a terminal in vscode (
ctrl+shift+`) make install- Try it!
python src/tagstr_site/htmldom.py
If you have vscode and Docker installed locally, you can:

This repo has a /docker/ submodule that contains dockerfiles used to build Lysandros' underlying cpython branch. Koudai manages the submodule and also has published the images to a registry at https://hub.docker.com/r/koxudaxi/python to make them easier to use.
