Need some assistance understanding [Community Event] Doc Tests Sprint #16292

Hello There.
Don’t know if this is the correct place to ask this but I am completely lost on how to proceeded with [Community Event] Doc Tests Sprint #16292 on GitHub. I have followed the instructions on the guidelines on what to do but I can’t seem to get the program to work. I ran doctest on the program and read the error messages to see what failed and tried to fix them, but they still wont pass. I’ve looked at different examples and other pull request others have done on [Community Event] Doc Tests Sprint #16292 but I can’t seem to wrap my head around it.
I’m completely lost, It seems like i don’t understand what is being asked of my, and I’m not even sure that I’m looking in the correct area. Any assistance and guidance would be much appreciated.
