operator: Functions corresponding to the standard operators.
The key-function patterns shown above are very common, so Python provides convenience functions to make accessor functions easier and faster. The operator module has itemgetter(), attrgetter(), and a methodcaller() funct
Both list.sort() and sorted() accept a reverse parameter with a boolean value. This is used to flag descending sorts. For example, to get the student data in reverse age order:

Unlike key functions that return an absolute value for sorting, a comparison function computes the relative ordering for two inputs.
