Fixing lint issues

https://github.com/Aatmaj-Zephyr/handtype/actions/runs/6675360221/job/18143258177

The issue links to a GitHub Actions run showing lint failures. Start by checking the repository's linting configuration (likely in a .yml file or setup.cfg/pyproject.toml) and the specific errors in the linked log. Run the linter locally (e.g., flake8, black, or pylint) on the codebase to reproduce the issues, then fix the formatting or style violations in the Python files.
