使用字典计数
https://www.nowcoder.com/practice/74f7e7f2344f4754bc56d862838cbfc3
这里有个点可以学习下
#方法一
# ls1 = list(input())# ls2 = [ls1.count(i) for i in ls1]
# print(dict(zip(ls1,ls2)))
#方法二
# from collections import Counter
# ls1 = input()
# print(dict(Counter(ls1)))
#方法三：
# ls1 = list(input())
# dict1 = {}
# for i in ls1:
# if i in dict1:
# continue
# dict1[i] = ls1.count(i)
# print(dict1)
# #方法四
# ls1 = list(input())
# dict1 = {}
# for i in ls1:
# if i in dict1:
# dict1[i] += 1
# else:
# dict1[i] = 1
# print(dict1)
#方法五
# ls1 = list(input())
# dict1 = {}
# for i in ls1:
# dict1[i] = dict1.get(i,0)+1
# print(dict1)
