f.close()

I recognize this error; you must have copied it from me!

As an aside, if you decide to use binary pickling (slightly more 
efficient):

  pickle.dump(test_list, f, bin=1)

and you're on Windows, you'll want to make sure your opens are binary:

  f = open("pickle.dat", 'wb')
   ...
  g = open("pickle.dat", 'rb')
