Well done, it's good to recognise that stage in your development.

Greetings,
I am at a point where I am familiar with variables, "if", "while", "for",
statements etc, as well as the basics of object oriented programming. Up to
this point I've mostly been following tutorials, which involves a lot of hand

Let's do some experimentation. Here's a list:

sense outside (and is a syntax error). Its purpose
is to return a value to the caller o

I was trying to rewrite the above as a function.
Unlike my code above, my function below did not return the first 5
rows, but just nothing:

my code below did not require a return statement, hence I was assuming
it wouldn't be needed in my function either.
