When writing docstrings, I was trying to decipher what the code was for,
rather than trying to figure out how to solve a problem. It involved some
backward thinking compared to writing code. I found it a bit easier than
writing code (although a lot of the methods referred to each other,
which made it a challenge sometimes).
I think I will include docstrings in the futre with more complex code, so
after writing a block of code, I don't forget what the code was for when
I come back to it later. I think it will be useful in the Games Project.
