Is it possible to make social interactions with XML tuning?

I don't know how to even make interactions yet. Our custom traits do come with an interaction XML file, but I don't know how to actually make an XML interaction, let alone python. I think the first thing I'm going to have to do is find a basic beginners python tutorial, them find a tutorial specifically for the Sims 4 and specifically for adding custom interactions (the latter DOES exist on MTS, but I think a general python tutorial is probably necessary first.)
