Let's call these "dependency definition files", even though some do more than just that.
I think in general it's a good idea to pin versions of your dependencies when you're building an application, it's different for libraries. My question is not about whether or not this is a good idea.
These dependency definition files allow for defining non-specific versions of those dependencies. For example: `cowsay >= 4.0`.
In my applications I'd like to force and remind myself to only create pinned dependencies. Ideally there would be a linter and git pre-commit hook so that I'm warned and blocked from creating dependencies that are not pinned.
In the JavaScript world there's a linter for `package.json` files that does exactly what I want: - [the tool](https://npmpackagejsonlint.org/) - [the rule](https://npmpackagejsonlint.org/docs/rules/dependencies/prefer-absolute-version-dependencies/)
Do tools like this exist for Python?
