python自学第12天之作业讲解

1，老男孩好声音选秀大赛评委在打分的时候呢，可以进行输入，假设:老男孩有10个评委，让10个评委进行打分，要求:分数必须大于5分，小于10分

count = 1
while count <= 10:
    fen = int(input("请第%s位评委评分:" % (count)))
    if fen < 5 or fen > 10:
        print("是不是傻!")
        continue
    else:
        print("第%s位评委打分为%s" % (count,fen))
    count = count + 1

2.电影投票，程序先给出一个目前正在上映的电影列表，由用户给每一个电影投票，最终 将该用户投票信息公布出来 lst =['金瓶梅','解救吾先生','美国往事','西西里的美丽传说'] 结果:{'金瓶梅':99,'解救吾先生':80,'美国往事':6,'西西里的美丽传说':23}

lst =['金瓶梅','解救吾先生','美国往事','西西里的美丽传说']
dic = {}
for i in lst:
    fen = input("请给%s电影打分:" % i)
    dic[i] = fen
print(dic)

3.车牌区域划分，现给出以下车牌，根据车牌的信息，分析出各省的车牌持有量

cars = ["鲁A12345","沪B45678","黑A12345","黑A12345"]
locals = {"鲁":"山东","沪":"上海","黑":"黑龙江"}
result = {}
for car in cars:
    first_name = car[0]
    location = locals[first_name]
    if result.get(location) == None:
        result[location] = 1
    else:
        result[location] = result[location] + 1
print(result)
