Append inside for?

Python supports both. vscode supports both. I'm allowed to have my personal preference.

In your Python journey, you will probably change some of your preferences to ease communication with other pythonistas. I strongly support formatting Python code with the black formatter, which frees your mind from code formatting. By default, Black uses spaces. Also the historic reindent script by Tim Peters can replace tabs by spaces automatically.
