Hi @dependabot[bot], thank you for your contribution! 🎉

This PR comes from your fork git-mastery/exercises on branch dependabot/uv/mypy-1.20.2.

Before you request for a review, please ensure that you have tested your changes locally!

Important

The previously recommended way of using ./test-download.py is no longer the best way to test your changes locally.

Please read the following instructions for the latest instructions.

Prerequisites

Ensure that you have the gitmastery app installed locally (instructions)

Testing steps

If you already have a local Git-Mastery root to test, you can skip the following step.

Create a Git-Mastery root locally:

gitmastery setup

Navigate into the Git-Mastery root (defaults to gitmastery-exercises/):

cd gitmastery-exercises/

Edit the .gitmastery.json configuration file. You need to set the following values under the exercises_source key.

{
    # other fields...
    "exercises_source": {
        "username": "git-mastery",
        "repository": "exercises",
        "branch": "dependabot/uv/mypy-1.20.2"
    }
}

Then, you can use the gitmastery app to download and verify your changes locally.

gitmastery download <your new change>
gitmastery verify
