问题描述

d = {'苹果':9，'橙色':3，'葡萄':22}

d = {'apple':9,'oranges':3,'grapes':22}

How do I make a list that has this sorted by largest to lowest value?

推荐答案

>>> d = {'apple':9,'oranges':3,'grapes':22}
>>> v, k = max((v, k) for k, v in d.items())
>>> k
'grapes'
>>> v

>>> items = sorted(((v, k) for k, v in d.items()), reverse=True)
>>> items
[(22, 'grapes'), (9, 'apple'), (3, 'oranges')]
