Recipe of the Week: Sorting with Closures
by Jeremy Jones
This week's recipe can be found here. It shows how to use closures to perform various sorting operations. Before you click on the link, let me point out the same thing as one of the commenters of this recipe: this recipe is pretty much obsoleted by mixing operator.itemgetter with list.sort(key=foo). I thought this recipe was interesting, though, because it showed a really good use for closures. Having a concrete idea of how a certain feature can be used sometimes helps to use the feature in other ways. Hopefully that will be the case here.
