I've not yet found an experience that matches the interactivity of DataCamp. They don't do simultaneous video and code, but they have helpful code feedback and the video slides are picture-in-picture, which I prefer to having to scroll through a video to lookup code screenshots. That said, DataCamp had a scandal a few years back and a lot of authors retracted content. I'll take a look at this.
