I agree. But I used it anyway, to make it easier to see that the sort and the groupby must be and are using the same key function. In this case I admit it's a not a huge readability win, but I was also following the "Do Not Repeat Yourself Rule", which makes the key function easier to refactor. > See in the example: > http://docs.python.org/lib/itertools-example.html > > So much stuff in libraries, so few we know.
