如何将文本文件中的行号赋给变量？

Question

我试图打印变量'Number'，但出现错误。在

'类型错误：列表索引必须是整数，而不是元组'

我不明白？什么是元组？我如何解决这个问题？ 如何将文本文件中的行号赋给变量？在

Answer 1

这一行：

Number = number, line in enumerate(ND, 1)

将两个值赋给Number这将产生一个元组。在

你可以这样做：

^{pr2}$

这将导致Number成为单个值，而不再是元组。在

Answer 2

当您执行Number = number, line in enumerate(ND, 1)时，您将Number定义为元组。您已经用for循环创建了number, line in enumerate(ND, 1)。为什么不直接用它呢？i、 e.AData[number]。在

仅举个例子，这就是您将Number设置为：

>>> 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number和{}的值（一个布尔表达式，要么在那里，要么不在那里）。在

您还有其他几个问题：

• 从1开始，而不是0，方法是将1提供给enumerate。在python中，列表索引从0开始。因此，如果一个列表的长度是1，那么[1]处的子索引实际上是越界的。您应该做enumerate(ND)，而不是从0开始。在
• 您需要.close()您的文件open()，或者像处理第一个文件一样使用with/as。在
• 您正在打开Email Address.txt两次。。。你是故意的吗？在

Answer 3

元组是一种“列表”。见文件：

http://docs.python.org/release/1.5.1p1/tut/tuples.html

您可能正在为var编号指定2个或更多个值
