某班英语成绩以字典形式存储为：{‘LeiLei‘:90,‘kim‘:88，......},根据成绩高地，计算学生排名。

from faker import Faker 
from random import randint

faker =Faker(‘zh‘)

#随机构造30个学生名称和成绩
studentsScore = {faker.name():randint(50,100) for i in range(30)}

print(studentsScore)


#利用zip合并为，(score,name)的形式，再排序
name = studentsScore.keys()
score = studentsScore.values()

print(sorted(zip(score,name),reverse=True))

{‘俞秀芳‘: 94, ‘党建国‘: 73, ‘叔莹‘: 83, ‘漆桂芝‘: 52, ‘虞丹‘: 66, ‘太荣‘: 62, ‘赫健‘: 59, ‘訾玉英‘: 99, ‘琴博‘: 66, ‘从桂芝‘: 68, ‘赫倩‘: 81, ‘农玲‘: 67, ‘于想‘: 59, ‘万春梅‘: 57, ‘窦兰英‘: 88, ‘乜梅‘: 88, ‘汪旭‘: 94, ‘金成‘: 83, ‘法芳‘: 78, ‘穆杰‘: 51, ‘秦军‘: 50, ‘申杰‘: 96, ‘哈玉‘: 50, ‘席莉‘: 78, ‘白红梅‘: 86, ‘葛凯‘: 59, ‘父建‘: 94, ‘郦强‘: 53, ‘政坤‘: 75, ‘严玉‘: 51}
