 Each chapter's examples are in their own directory. In some chapters, you'll find multiple snippets in a single module. These won't always produce output when you run them, and are occasionally meant only as snippets to demonstrate a concept. In later chapters, some modules act as an entrypoint to run a program from the command line, importing other modules along the way. Follow along in the book for more context!
