Ricardo Medina did everyone a great service by posting his Python translations of some of the NetLogo procedures. But there's more to be done. Having a Python translation is not the same as an explanation -- otherwise, you would all understand every Python program you came across. An explanation should be in English. And, of course, there is more to the NetLogo code than those three procedures. I hope to see contributions from others.

And as I keep saying, if you have questions, please post them on the Forum!
