Question

运行我的代码的这一部分时，出现上述错误，csv文件每行具有3个值，首先是名称，然后是ID号，最后是数字分数。我不知道为什么说列表索引超出范围。

当我将for循环内的代码更改为仅打印行时，它会将其打印出来，就好像它是具有3个值的列表一样。

csv文件如下

sean，12,15

harry，132,12

ben，3322,11

等，

我仔细检查了文件，看是否每个行中没有3个值，但事实并非如此。每行正好有3个值，以2个逗号分隔。

 points=[]
 names = []
 ids = []
 quiztakers = 0 
 totalscore = 0 
 with open('scoreFilecsv','r+') as score:
     reader = csv.reader(score,delimiter=',')
     for row in score:

         point = row[2]
         totalscore += point
         quiztakers += 1
         name = row[0]
         ids1 = row[1]
         points.append(point)
         names.append(name)
         ids.append(ids1)

Answer 1

下面的代码是我尝试过的并且有效

points=[]
names = []
ids = []
quiztakers = 0 
totalscore = 0
i = 0
score = ["sean",12,15, "harry",132,12]
new_row = []
for row in score:

    if i != 0 and i%3 == 0:
        point = new_row[2] 
        totalscore += point
        quiztakers += 1
        name = new_row[0]  
        ids1 = new_row[1]  
        points.append(point)
        names.append(name)
        ids.append(ids1)
        new_row = []
    new_row.append(row)
    i += 1
else:
    point = new_row[2] 
    totalscore += point
    quiztakers += 1
    name = new_row[0]  
    ids1 = new_row[1]  
    points.append(point)
    names.append(name)
    ids.append(ids1)
    new_row = []

print(names)
print(points)
print(ids)

输出：
```
['sean', 'harry']
[15, 12]
[12, 132]
```
查看您的代码，我相信row列表是因为row列表的长度在某些时候会确定小于2

我认为您想在此处成为reader变量而不是score变量（我假设正在查看您的代码，但我不确定，因为我不知道您的代码是什么输入在EXCEL中是同一行还是不同行？）

 points=[]
 names = []
 ids = []
 quiztakers = 0 
 totalscore = 0 
 with open('scoreFilecsv','r+') as score:

     reader = csv.reader(score,delimiter=',')
     for row in score: # (Changing this line) for row in reader

         point = row[2] # you may be getting error here
         totalscore += point
         quiztakers += 1
         name = row[0]  # you may be getting error here
         ids1 = row[1]  # you may be getting error here
         points.append(point)
         names.append(name)
         ids.append(ids1)

但是看看您对问题输入的描述，这就是我要做的

 points=[]
 names = []
 ids = []
 quiztakers = 0 
 totalscore = 0
 i = 0
 with open('scoreFilecsv','r+') as score:
     reader = csv.reader(score,delimiter=',')
     new_row = []
     for row in reader:

         if i != 0 and i%3 == 0:
             point = new_row[2] 
             totalscore += point
             quiztakers += 1
             name = new_row[0]  
             ids1 = new_row[1]  
             points.append(point)
             names.append(name)
             ids.append(ids1)
             new_row = []
         new_row.append(row)
         i += 1
    else:
        point = new_row[2] 
        totalscore += point
        quiztakers += 1
        name = new_row[0]  
        ids1 = new_row[1]  
        points.append(point)
        names.append(name)
        ids.append(ids1)
        new_row = []

自从您更新问题和输入内容以来：我将使用以下代码

 points=[]
 names = []
 ids = []
 quiztakers = 0 
 totalscore = 0 
 with open('scoreFilecsv','r+') as score:

     reader = csv.reader(score,delimiter=',')
     for row in reader: # (Changing this line) for row in reader
         row = row.split(",")
         point = row[2] 
         totalscore += point
         quiztakers += 1
         name = row[0]  
         ids1 = row[1]  
         points.append(point)
         names.append(name)
         ids.append(ids1)

收到错误消息：列表索引超出范围
