Modified square.py to use a for loop in order to simplify the code block.

1) I think coming from for loops in JS makes python for loops
loops look a little weird sometime. But also utilizing list items as distances for Turtle is really cool, I didnt even think of that,
im wondering if you could do the same on JS. It just looks a little different and obviously there are different use cases.
