列出索引超出范围（有时失败有时有效）

Question

我正在从文件中读取数据。内容：time-id-data， 当我在MAC上运行时，它运行良好，但是在Linux上，有时它有时会失败。 错误是“ IndexError：列表索引超出范围” 像这样的数据：

当您的values的元素少于一个时，即表示values = line.strip().split("\t")，line根本没有\t时，会发生此错误。

也许是空行？或linux格式问题。

您可以在使用前检查len中的values：

if len(values) < 9:
    continue

或尝试以下操作：

import string
values = line.strip().split(string.whitespace)

无法重现您的病情，因此请尝试一下。
