您可以执行以下操作：
from itertools import takewhiledef get_items_upto_count(dct, n): data = dct.most_common() val = data[n-1][1] #get the value of n-1th item #Now collect all items whose value is greater than or equal to `val`. return list(takewhile(lambda x: x[1] >= val, data))test = Counter(["A","A","A","B","B","C","C","D","D","E","F","G","H"])print get_items_upto_count(test, 2)#[('A', 3), ('C', 2), ('B', 2), ('D', 2)]
