"pylint.importStrategy": "fromEnvironment"

When you start your project, the first thing you will likely do is activate your virtual environment or open up a container to develop in (like

There are many packages for code quality. At the time of this post, VS Code and its active extension-contributing community supports , . The Ruff linter was created from the . The VS Code team encourages community contributed packages and you can
