# Example from PEP 265 - Sorting Dictionaries By Value # Counting occurences of letters d = {'a':2, 'b':23, 'c':5, 'd':17, 'e':1} # operator.itemgetter is new in Python 2.4 # `itemgetter(index)(container)` is equivalent to `container[index]` from operator import itemgetter # Items sorted by key # The new builtin `sorted()` will return a sorted copy of the input iterable. print sorted(d.items()) # Items sorted by key, in reverse order # The keyword argument `reverse` operates as one might expect print sorted(d.items(), reverse=True) # Items sorted by value # The keyword argument `key` allows easy selection of sorting criteria print sorted(d.items(), key=itemgetter(1)) # In-place sort still works, and also has the same new features as sorted items = d.items() items.sort(key = itemgetter(1), reverse=True) print items
