\ newline转义序列在python中是什么意思? [英] What does the \newline escape sequence mean in python?

问题描述

我在中找到了序列\newline python文档中的转义序列列表.我想知道它是如何使用的以及用于什么目的.至少在我的解释器中，这似乎只是被解释为'\n' + 'ewline':

I found the sequence \newline in a list of escape sequences in the python documentation. I wonder how it is used and for what. At least in my interpreter it seems this is just interpreted as '\n' + 'ewline':

>>> print('\newline')

ewline

推荐答案

它是指实际的换行符，即字符代码为"16"(0x10)的字符，而不是文本序列换行符".

It refers to the actual newline character - the one with character code "16" (0x10) - not the text sequence "newline".

因此，示例如下:

print("a\
b")

在这里，反斜杠由字符串内的换行符接续，并且打印的内容只是"ab"而没有任何区别.

Here, the backslash is succeeded by the newline, inside a string, and what is printed is just "ab" with nothing apart.

与\n不同-在这里，反斜杠后面的字符是n(0x6e)，并且在解析字符串时，此序列转换为\x10.在\<newline>上，源字符串包含\x10字符，并将其替换为空字符串.

it differs from \n - in here, the characer following the backslash is n (0x6e), and this sequence is translated to \x10 on parsing the string. On \<newline>, the source string contains the \x10 character and that is replaced by an empty string.

如果该页面上的文档显示的是\<newline>而不是\newline，则可能会更清晰.

Maybe the documentation on that page would be more clear if it would read \<newline> instead of just \newline.
