simplifying code

Hi Yedidya,

I'm making what's called a 'Pull Request' on your code. I made a change, and if you like it, you can 'merge' it in to your code. See if you can figure out how to do that on Github. If you do it, then you'll have to run the command:

git pull

in your terminal for your code on your computer to be updated as well.

Let me know if you need any help.
