If this is an actual cut and paste: your retrieve_rankdata is not indented
properly here. The 'def' needs to line up exactly with the other fields and
methods defined in Problem. It would be better form also to make its
contents indented a consistent amount rather than having it be so much more
dramatically indented than everything else.

Fix the indentation and I expect the problem will go away. Also, be careful
not to mix tabs and spaces, that will also lead to difficulties in Python.
Best to stick with spaces and never use tabs.
