Hi Yan, pn = []
is an empty list. pn[i] += d tries to access an element of that list. I'm not quite sure you should be creating a pn = [] in every for loop iteration, neither. This looks like a Python programming issue to me. It's probably a good idea to practice a little bit on your python skills; python.org actually has good Python2 tutorials!
