统计重复字符串并排序

string = 'aovbzoasvaobvdoaobgvo;sogvosov;svgoas;shvbpe;;svoovohoaosobvboeaso'

string_set = list(set(string))
print(string_set)

conuts = list(map(string.count,string_set))
print(conuts)
strings = list(zip(string_set,conuts))
print(sorted(strings,key=lambda x: x[1],reverse=True))

结果如图：
