Splitting a string separated by "\r\n" into a list of lines?
提问by ahhtwer
I am reading in some data from the subprocess module's communicate method. It is coming in as a large string separated by "\r\n"s. I want to split this into a list of lines. How is this performed in python?
我正在从子进程模块的通信方法中读取一些数据。它以一个由“\r\n”分隔的大字符串形式出现。我想把它分成一个行列表。这是如何在python中执行的？

Use the splitlines method on the string.
对字符串使用 splitlines 方法。
From the docs:
从文档：
str.splitlines([keepends])Return a list of the lines in the string, breaking at line boundaries. Line breaks are not included in the resulting list unless keepends is given and true.
str.splitlines([keepends])返回字符串中的行列表，在行边界处断开。结果列表中不包含换行符，除非给出了 keepends 并且为 true。
This will do the right thing whether the line endings are "\r\n", "\r" or "\n" regardless of the OS.
无论行尾是“\r\n”、“\r”还是“\n”，无论操作系统如何，这都会做正确的事情。
NB a line ending of "\n\r" will also split, but you will get an empty string between each line since it will consider "\n" as a valid line ending and "\r" as the ending of the next line. e.g.
注意 "\n\r" 的行结尾也将拆分，但每行之间会得到一个空字符串，因为它会将 "\n" 视为有效的行结尾，将 "\r" 作为下一行的结尾. 例如
>>> "foo\n\rbar".splitlines()
['foo', '', 'bar']

s = re.split(r"[~\r\n]+", string_to_split)
This will give you a list of strings in s.
这将为您提供 s 中的字符串列表。

Check out the doc for string methods. In particular the split method.
查看字符串方法的文档。特别是split方法。
