I guess, you can not simply += on lists.

You should probably use the list method extend - otherwise the original list will not be modified:

includes.extend(["BaseHTTPServer", ""])

EDIT: (Thank @ThomasK)

+= works fine - I only had an online Python interpreter that did not work correctly. (I have no python install on my Windows installation so I had to check online).
