Best Practices for Python Main Functions

Now that you know the differences between how Python handles the various execution modes, it’s useful for you to know which best practices you can implement. You’ll learn about four best practices you can use to make sure that your code can serve a dual purpose:

  1. Put most code into a function or class.
  2. Use __name__ to control execution of your code.
  3. Create a function called main() to contain the code you want to run.
  4. Call other functions from main().

Is it tmux or some other terminal setup you use in your presentation?

@Gregory: I believe this is the built-in terminal of the VS Code editor. We have a dedicated course on it here :)

What happens if you import more than one module with a main() function? Does the namespace of the module keep the interpreter from getting confused?

Very often on the top of a file one defines module-level variables. Does it mean they become available from the scope of the importing script? Can they override each other?

Do you record the audio and video separately or is it in one go?
