如何按值和优先级对dic排序

Question

因此，我是Python的初学者，面临一个问题。问题是，我有以下的意见：

topperformer1 = {"Olivia":19, "Maria":18, "Pedro":15, "Nuno":17, "Julia":19, "Vasco":17, "Carla":18}

现在我想打印3个最高等级（值），但是如果我在值之后对dict排序并打印它，我只会得到没有键的值

我希望你能帮助我，并向我问好

Answer 1

使用collections.Counter

Ex:

from collections import Counter

topperformer1 = Counter({"Olivia":19, "Maria":18, "Pedro":15, "Nuno":17, "Julia":19, "Vasco":17, "Carla":18})
print(topperformer1.most_common(3))
#  > [('Olivia', 19), ('Julia', 19), ('Maria', 18)]
