I have quite a few non-technical colleagues who know just enough Python to Get Shit Done.
My father (a writer) taught himself R for research purposes and is productive with it.
Universal Paperclips has a super-basic JavaScript codebase[0] but was a really popular game.
Thing is, if you search "how to do X in Python" you're going to get a bunch of resources aimed at professionals because they're the ones looking for that stuff most of the time. That doesn't mean the resources are prohibitively complex, they're just for people solving a different problem.
