To ensure that the files can run on a cross-platform, and since most of the deployment platforms are Linux based, we need to ensure that all files are closed with a similar end of line (EOL) character, which is.To override, VS code provides a setting to format the script every time we save it.

We have configured black, but to use it, we would have to run black via command prompt manually every time after a file is saved.
