Getting Started with Python Scripting

I'm a total newbie and managed to complete one of the tutorials on python script reloading in the Sims 4 game without having to restart the whole game. But I have one question though: is there any way to reload package files in the Sims instead of just python files? I hope that's not a lame question. I've been learning how to make traits and it would be so much faster to test them by using the reload script instead of restarting the game.

I do hope to learn more about making mods.

Here is the tutorial that I completed and IT DOES WORK for py files. I just wish it would for package files.

If I missed something and someone already asked this, I do apologize.

Thank you,
