I've been interested in using more numpy, scipy, pandas and such for puzzles and code studies. I thought others might find this pandas example interesting, compared to the generic python solution. The groupby().first() fit the puzzle well. It could also have used other groupby options, e.g, mean(), depending on the goal.
