当您在枚举（ND，1）中执行
Number=Number时，将Number
定义为元组。您已经使用for
循环创建了枚举（ND，1）编号行。为什么不直接用它呢？i、 e.AData[number]
仅举一个例子，这就是您将Number
设置为的内容：
>>> for x, y in enumerate([1,2,3], 1):
print x, y in enumerate([1,2,3], 1)
1 False
2 False
3 False
它是一个元组，包含来自for
循环的数字，以及enumerate（ND，1）
中行的值（一个布尔表达式，要么在那里，要么不在那里）
您还有其他几个问题：
- 通过将
1
提供给枚举
，可以从1
开始number
，而不是0
。在python中，列表索引从0
开始。因此，如果列表的长度是1
，那么[1]
处的子索引实际上是超出范围的。您应该从0
开始执行enumerate（ND）
- 您需要
.close（）
您打开的文件（）
，或者像处理第一个文件一样使用和
/
您正在打开电子邮件地址.txt
两次。。。你是有意的吗
在这一行：
Number = number, line in enumerate(ND, 1)
将两个值赋给Number——这将生成一个元组
你可以这样做：
Number, junk = number, line in enumerate(ND, 1)
这将导致数字成为单个值，而不再是元组。元组是一种“列表”。见以下文件：
您可能正在为var编号分配2个或更多值请提供完整的回溯。但是不需要设置Number=Number，line…
（这使它成为一个元组）；您已经有行号了，只需使用number
。这是完整的代码吗？如果有帮助，我可以粘贴完整的代码：）问题只出现在本节中，这就是我只打印此代码的原因subroutine@PythonBeginner对粘贴整个代码。我已经提供了完整的代码供您查看@2RS2TS。它出现了一个错误：indexer错误：list index out of ofrange@PythonBeginner对于AData
和文件中的其他行的内容，而不是您发布的代码的一部分，这是一个完全不同的问题。@pythonbeginer我猜您的Name.txt
中的行数多于其他文本文件中的行数。因此，索引器
（编号
大于len（AData）
）Ok将删除文本文件中所需行以外的所有其他行。我已经删除了这些行，只留下最上面的行，错误仍然出现@2rs2ts现在我真的很困惑，到底是什么问题呢？不，我不是故意要打开Email Address.txt两次的，谢谢你指出这一点。我将切换到一个，并使其与，所以它会自动关闭@2rs2tsI得到相同的错误，当我尝试@2rs2ts的建议。索引器错误：列表索引超出范围修改后的代码仍有以下行：Number=Number，枚举（ND，1）
中的行，这意味着数字是元组而不是整数，因此不能是列表索引。
