Question

我正在尝试读取文件并将内容放入列表中。我之前已经完成了这个时间并且它已经工作但是这次它会抛出错误“列表索引超出范围”。

代码是：

with open("File.txt") as f:
scores = []
for line in f:
    fields = line.split()
    scores.append( (fields[0], fields[1])) 
    print(scores)

文本文件采用格式;

Alpha:[0, 1]
Bravo:[0, 0]
Charlie:[60, 8, 901]
Foxtrot:[0]

我不明白为什么它会给我这个问题。是因为每件商品都有多个价值吗？或者我的文本文件中有冒号这个事实？

如何解决这个问题？

如果我理解你，这段代码会打印出你想要的结果：

import re

with open("File.txt") as f:
    # Let's make dictionary for scores {name:scores}.
    scores = {}

    # Define regular expressin to parse team name and team scores from line.
    patternScore = '\[([^\]]+)\]'
    patternName = '(.*):'

    for line in f:
        # Find value for team name and its scores.
        fields = re.search(patternScore, line).groups()[0].split(', ')
        name = re.search(patternName, line).groups()[0]

        # Update dictionary with new value.
        scores[name] = fields 

    # Print output first goes first element of keyValue in dict then goes keyName
    for key in scores:
        print (scores[key][0] + ':' + key)

您将收到以下输出：

60:Charlie
0:Alpha
0:Bravo
0:Foxtrot

IndexError：列表索引超出范围，scores.append（（fields [0]，fields [1]））
