Does pip provide a TOML parser for python 3.9?

Question

I want to parse TOML files in python 3.9, and I am wondering if I can do so without installing another package.

Since pip knows how to work with pyproject.toml files, and I already have pip installed, does pip provide a parser that I can import and use in my own code?

Answer 1

For 3.9, pip vendors tomli:

from pip._vendor import tomli

For consenting adults, importing the vendored module should work as usual. However, this is an implementation detail of pip, and it could change without a deprecation period at any moment in a future release of pip. Therefore, for anything apart from a quick hack, it would be safer to install tomli (or some other TOML parser) into the site instead.
