Question

需要安排数学测验的分数：

- 按字母顺序排名，得分高 - 从最高分到最高分 - 从平均得分最高到最低如果可能的话，我想用字符串来做这个，如果你能告诉我怎么做，我将不胜感激。我正在考虑使用字符串，但我不知道你是怎么做的。我到目前为止的代码是：

import random
def start_quiz():
    print("Welcome to my Maths quiz")
#this creates a subroutine to enter the users name
def get_name():
    global name
    global group

    name=input("What is your name?")
    while name=="":
          name=input("What is your name?")
          group=input("What class are you in-1,2 or 3?")
    while group=="":
          group=input("What class are you in?")
    print("Hello " + name)

def questions():
    global score
    global questionnumber
    score=0
    questionnumber=0
    while questionnumber<10:
        questionnumber=questionnumber+1 
        operatorlist=['+','-','*']
        num1=random.randint(1,10)
        num2=random.randint(1,10)
        op=random.choice(operatorlist)
        if op=='-' and num2>num1:
            expression="%d %s %d" % (num2,op,num1)
        else:
            expression="%d %s %d" % (num1,op,num2)
        answer=eval(expression)
        enter_answer=1
        while enter_answer==1:
            try:
                useranswer= int(input(expression))
                enter_answer=0
            except ValueError:
                print("that was not a number, please re enter your answer")
        answer=int(answer)
        if useranswer==answer:
            print("well done")
            score=score+1
            print(" ")
        else:
            print("incorrect the correct answer is %d " % (answer))




def end_quiz():
    print("The quiz is now over")
    print("Well done " + name+". Your score is %d out of 10" % (score))

def savethescore():
    global score
    score=str(score)
    if group=='1':
        file=open("Scoreforclass1.txt",'a')
        file.write("\n")
        file.write ("Name: "+name+"\n")
        file.write('Class: '+group+'\n')
        file.write("Score: "+score+"/10\n")
        file.close()
    elif group=='2':
        file=open("Scoreforclass2.txt",'a')
        file.write("\n")
        file.write ("Name: "+name+"\n")
        file.write('Class: '+group+'\n')
        file.write("Score: "+score+"/10\n")
        file.close()
    else:
        file=open("Scoreforclass3.txt",'a')
        file.write("\n")
        file.write ("Name: "+name+"\n")
        file.write('Class: '+group+'\n')
        file.write("Score: "+score+"/10\n")
        file.close()


 def play_again():
     again= input("would you like to play again? y for yes and n for no")
     while again not in ['Y','y','N','n']:
         again = input("please enter 'Y' or 'N'")
     if again== 'y' or 'Y':
        do_the_quiz()
     else:
         print("cheers lad thanks for playing")
         exit()


def do_the_quiz():
    start_quiz()
    get_name()
    questions()
    end_quiz()
    savethescore()
    play_again()

do_the_quiz()

如果可能的话，你可以尝试使用字符串，因为我尝试使用csv文件，但它太复杂了。提前谢谢。

这应该适合你。

干杯！
