I have heard of pickle, but never used it. I looked it up in Learning
Python (O'Reilley p 236). The example they give shows that you need to
pickle your object, and put it in a file with pickle(dump(D,F) where D is a
dictionary in the example and F is a file object. You then can retrieve it
with pickle.load(F). The thing you are trying to load is a file that was a
copy of the contents of the url. It is html, and not 'pickled'
I think you are missing a line or two of code from your example tutorial
