为什么我在尝试将记录中的项设为整数时会出错？

Question

我的代码有点问题。这段代码的目的是让用户的分数与他们的名字在一个元组中配对，然后按字母顺序、数字顺序对这些分数排序，最后求平均值。我在完成这个项目的边缘，但这个错误继续阻碍我，所以我希望获得编程社区的帮助。你知道吗

if Class == 'Year5S':
    Year5S = open ('Year5S.txt', 'r')
    Year5S = Year5S.read()
    print ('\nThe others in your class have scored the following:\n' + Year5S + '\n')

    Year5Sa = open ('Year5S.txt', 'a')
    Year5Sa.write (Name)
    Year5Sa.write (",")
    Year5Sa.write (str(Score))
    Year5Sa.write (",")
    Year5Sa.close()
    print("Would you like to see the scores sorted Alphabetically, Numerically or Averaged?")
    order=input()

i=0
record={}

itemsS = Year5S.split(",")
length = len(itemsS)
length = length-1
average_dict={}
average = {}



for i in range(0,length,2): #We are incrementing by 2 because we want to jump to every other item in the list (names of teams)
        Firstname = itemsS[i]
        score = itemsS[i+1]
        record[Firstname]=score
        if Firstname not in average_dict:
            average_dict[Firstname] = []
            average_dict[Firstname].append(score)
        if len(average_dict[Firstname]) >3:
            average_dict[Firstname].pop(0)
        if Firstname not in average:
            collection = sum(average_dict[Firstname])/len(average_dict[Firstname])
            collection = round(collection)
            average[Firstname] = collection

sorted_average = sorted(average.items(), key=lambda x: x[1], reverse = True)



sorted_Alist=sorted(record.items(), key=lambda x: x[0])



sorted_Nlist=sorted(record.items(), key=lambda x: x[1])



if order == "Alphabetically":
        print(sorted_Alist)

elif order == "Numerically":
        print(sorted_Nlist)

elif order == "Averaged":
        print(sorted_average)

我继续得到这个错误。你知道吗

 Traceback (most recent call last):
  File "C:\Users\user\Downloads\Arithmetic Game Experimental.py", line 125, in <module>
    collection = sum(average_dict[Firstname])/len(average_dict[Firstname])
TypeError: unsupported operand type(s) for +: 'int' and 'str'

我试图使记录为整数，但这是一个失败的尝试，我得到了这个错误。typeerror: int() argument must be a string or a number, not 'list'

如何将记录设为整数，以便将整数内的分数相加，然后除以整数内的分数得到平均值？提前谢谢。你知道吗

Answer 1

替换

score = itemsS[i+1]  

由

score = int(itemsS[i+1])
