Question

对于下面的代码，我总是收到错误ValueError: need more than 1 value to unpack。它是从txt file读取的，有5个不同的内容，所以肯定它有超过1行。

 with open("People.txt", 'r') as inFile:
    for line in inFile:
       ip,user,password = line.strip().split(',')

文本文件如下所示：

 ip,username,password

然后空行是问题。您应该添加空白支票线。 - 羊皮纸

示例有用的食谱：

In [17]: with open("src.txt") as f:
    ...:     for f_ in f:
    ...:         if f_.strip(): # One quick way to check for blank lines.
    ...:             one_,two_ = f_.strip().split(",")
    ...:             print one_, two_

您可以在文件末尾添加换行符。你可以做得更强大，例如那样。

with open("People.txt", 'r') as inFile:
    for line in inFile:
        if line.count(',') == 2:
            ip,user,password = line.strip().split(',')

在python中解压缩的ValueError
