This is my level of knowledge of Python right now. I wanted to use this little program in a presentation to showcase control flow, by explaining how Python interpreter goes through lines of code and which line gets executed first. That’s why the strings are numbered.

But merely printing messages seems so bland. What can be done in this code to make it show more than string output to demonstrate control flow?
