Hey - thanks for checking the book out.

Yeah, you are correct---the book does not cover packaging a Python program as a click and run style executable.

It's definitely a tricky problem. (Depending on the audience for the tools (e.g. if it's developers), one potential option might be to package your code in a Docker image and distribute it that way---although that's not without its own drawbacks.)

Other commenters have posted potential tools to check out too.
