I find the problem with these courses that there is a gap if you want to head over to applications. You then perphaps need to know how to deal with enviroments, pip, locate suitable modules.
But to get the basics under control this way is pretty nice.
Most of what you're saying there sounds quite foreign to me so there might be a gap yeah. This at least seems to work well for learning the syntax which is mostly what I'm after right now.
