python - 如何按值对 dic 进行排序并打印

Question

所以我是 Python 的初学者并且面临一个问题。问题是我有以下字典：

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字典进行排序并打印它，我只会得到没有键的值。

我希望你能帮助我和最好的问候

Answer 1

利用collections.Counter

前任：

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)]
