python练习之编程小练习

from collections import Counter

data = list(input("请输入字符串：").split(','))
# data = ['hello','world','www','aaabbb']

for i in data:
    res = Counter(i)
    # Counter()为计数器，返回Counter类型，可以使用dict转化成字典类型
    # print(type(res))
        #类型： Counter({'a': 3, 'g': 3, 'c': 2, 'f': 2, 'b': 1})
    # print(res)
    max_len = 0
    for key in res:
        # print(key)，key为键
        if max_lenn/2:
        data.remove(i)
#         把重复次数大于字符串字数的删除掉

print(data)
