Hello, it seems this PR is formatted incorrectly.

This is okay! This repository uses CI (Continuous Integration) to ensure that all library files are formatted properly. It uses a program called black to accomplish this. You can download it by doing pip install -U black==22.6.

The settings for black are located in the root directory of the project where the pyproject.toml is located. Make sure to run black discord/ examples/ in the directory where the pyproject.toml is located and it should all fix the formatting issues.

Thanks!
