Initially my idea was to just make purely theoretical videos. But I think that in some topics (where there is a clear algorithm for example) it might be helpful to show some Python implementation. Even in that case, I prefer the video overall to be more math focused. So going forward, I will add code if it seems necessary to complete the explanation. For example, in causality, the concept of avg. treatment effects can be explained through theory, but a concrete Python example will make it much clear for anyone watching what exactly is happening.
