The Sims 4: How to Update your Script Mods for the November Update

Sims4Studio’s Tech Lead Andrew has posted a very useful tutorial on how to update all of your Script Mods for the upcoming update release for The Sims 4.

As warned by SimGuruModSquad about a month ago, the upcoming update for The Sims 4 will be upgrading the programing language used for some of the game’s basic functions from Python 3.3.5 to Python 3.7.0. This means that every single script mod created for the game will be completely obselete and won’t even be recognized by the game’s engine considering that the file extensions will switch from .pyo to .pyc.

Luckily, this tutorial will teach you how to easily upgrade your Script Mod and prepare it for the upcoming update.


This tutorial will show you how to install the required tools, extract EA python scripts, edit custom python scripts, and compile them to share as a mod. You will be using a free program called PyCharm to edit the python files. Please note, this tutorial assumes some familiarity with python and is not meant as a substitute for lessons/tutorials in python coding. It will show the Sims 4-specific steps of making a script mod.

  • Does script mod include custom content objects or just things like trait alterations, for example? Also, is this tutorial meant for people who downloaded the mod to modify it or is it the original creator that is supposed to update and then we have to redownload it?

    • This is meant for the original creators to update. This has to do with files that include .ts4script files along side a .package file. Other items that do not have changes to script will not be affected by the python update.

  • Does anyone know of any actual tutorial that shows you how to update the tscripts? I have no experience in python but i’ve downloaded programs which i believe can allow you to do so, I just don’t know how. I wouldn’t mind taking it upon myself to update them, instead of waiting around for the original creators to do so. Some of the game mods I use where created months ago, and the original creators are no longer active.

    • if you do find a tutorial, could you share it? been having issues trying to learn all of this just to update my favorite mods

  • Hey there, I think your website might be having browser
    compatibility issues. When I look at your blog site in Ie,
    it looks fine but when opening in Internet Explorer, it has some overlapping.

    I just wanted to give you a quick heads up! Other then that, wonderful
