8: Using VS Code and completing my first program

In this video, I continue making my first program more flexible. I finish rewriting my mapperdata.py module to read the YAML config file and build a data structure based on its contents. I also introduce the Visual Studio Code text editor, which I'll be using from now on. Before watching this video, I recommend you review the following short videos:
