enter code hereafter various failed attempts to make keyframes work to my liking in my first blender-script work I request your help 🥲

So I am working on a Dataviz:

1. I load Data into Blender and create an object.
2. Then I transform the object according to the data.
3. Now I have 4 different years, Year1 - Year4. I want to show each transformation, for each Year with keyframes (one keyframe shows one year location, scale transformation)
4. and all of the keyframes of the 150 country-Objects should start and end at the same time.

...But the mechanics of the for-loop are laughing at my face - I got everything working except for the keyframes which drives me mad 🤪 so If I use an offset the transformations for each object are working perfectly, but they don't start at the same time - if I try and use iteration, I have neat keyframes, but no animation (I will only show Year4). How do I get out of this Mess? 😓

See for yourself on github: https://github.com/SaraHeitz/blenderpython

Version with offset: https://www.youtube.com/watch?v=QTyYj4ZKNBA

Version with iteration:

So in short I would love for this Dataviz to animate the country for each year, and set a keyframe for the according values, like the youtube animation, but start and end at the same time for every object: https://www.youtube.com/watch?v=QTyYj4ZKNBA

this is a reduced version of the whole code with iteration:
