Remove from python string
提问by directedition
When you run something through popenin Python, the results come in from the buffer with the CR-LF decimal value of a carriage return (13) at the end of each line. How do you remove this from a Python string?
当您popen在 Python 中运行某些内容时，结果来自缓冲区，每行末尾带有回车符 (13) 的 CR-LF 十进制值。如何从 Python 字符串中删除它？
回答by Benjamin Pollack
You can simply do
你可以简单地做
s = s.replace('\r\n', '\n')
to replace all occurrences of CRNL with just NL, which seems to be what you want.
用 NL 替换所有出现的 CRNL，这似乎是您想要的。

buffer = "<text from your subprocess here>\r\n"
no_cr = buffer.replace("\r\n", "\n")

If they are at the end of the string(s), I would suggest to use:
如果它们在字符串的末尾，我建议使用：
buffer = "<text from your subprocess here>\r\n"
no_cr = buffer.rstrip("\r\n")
You can also use rstrip() without parameters which will remove whitespace as well.
您也可以使用不带参数的 rstrip() 来删除空格。

Actually, you can simply do the following:
实际上，您可以简单地执行以下操作：
s = s.strip()
This will remove any extraneous whitespace, including CR and LFs, leading or trailing the string.
这将删除任何无关的空白，包括 CR 和 LF，字符串的前导或尾随。
s = s.rstrip()
Does the same, but only trailing the string.
做同样的事情，但只是尾随字符串。
That is:
那是：
s = ' Now is the time for all good... \t\n\r "
s = s.strip()
s now contains 'Now is the time for all good...'
s now 包含“现在是一切顺利的时候......”
s = s.rstrip()
s now contains ' Now is the time for all good...'
s 现在包含“现在是一切顺利的时候了......”

You can do s = s.replace('\r', '')too.
你也可以s = s.replace('\r', '')。
回答by dumbass
replace('\r\n','\n') should work, but sometimes it just does not. How strange. Instead you can use this:
replace('\r\n','\n') 应该可以工作，但有时却不能。多奇怪。相反，您可以使用它：
lines = buffer.split('\r')
cleanbuffer = ''
for line in lines: cleanbuffer = cleanbuffer + line
