如何对测验完成3次后得到的分数进行排序？

Question

当用户参加此测验三次时，我如何对他们获得的分数进行排序，从最高分到最低分？另外，当代码运行时，我如何按字母顺序对用户名进行排序，并将其分数放在其名称旁边？

school_data = []
for x in range (0,3):
    quiz = dict()
    print ("Enter your name")
    quiz['name'] = input()
    print ("what class")
    quiz['class_code'] = input()

    print("1. 9+10=")
    answer = input()
    answer = int(answer)

    if answer == 19:
        print("correct")
        score = score + 1
    else:
        print("wrong") 
    print("2. 16+40=")
    answer = input()
    answer = int(answer)
    if answer == 56:
        print("correct")
        score = score + 1
    else:
        print("wrong")

    print("3. 5+21=")
    answer = input()
    answer = int(answer) 
    if answer == 26:
        print("correct")
        score = score + 1
    else:
        print("wrong")

    print("4. 5-6=")
    answer = input()
    answer = int(answer)
    if answer == -1:
        print("correct")
        score = score + 1
    else:
        print("wrong")

    print("5. 21-9=")
    answer = input()
    answer = int(answer)

    if answer == 12:
        print("correct")
        score = score + 1
    else:
        print("wrong")
    quiz['score'] = score
    school_data.append(quiz)

Answer 1

您可以使用以下命令按分数对school_data列表进行排序

sorted_school_data = sorted(school_data, key=lambda k: k['score'])

默认情况下，首先对分数最低的进行排序，所以从最高到最低只需这样做

sorted_school_data = sorted(school_data, key=lambda k: k['score'])[::-1]

要打印分数和姓名，您可以执行以下操作

for i in sorted(school_data, key=lambda k: k['name']):
    print('%s:%s' %(i['name'], i['score']))
