In this section we’re going to build the sample application with Python, following the items that have already been split up into parts we discussed earlier.

In reality, when I built the sample application to use as an example, I built these three parts in parallel. Because when building the core part, additional utils or runtimes show up, or runtimes need some setup so we add it into core. And in this section I won’t redo the file/folder creation steps in code anymore.
