您如何在Python文件中写入特殊字符("\ n"，"\ b"，...)? [英] How do you write special characters ("\n","\b",...) to a file in Python?

问题描述

我正在使用Python将一些纯文本处理到LaTeX中，因此我需要能够将\begin{enumerate}或\newcommand之类的内容写入文件.但是，当Python将其写入文件时，它将\b和\n解释为特殊字符.

I'm using Python to process some plain text into LaTeX, so I need to be able to write things like \begin{enumerate} or \newcommand to a file. When Python writes this to a file, though, it interprets \b and \n as special characters.

如何让Python将\newcommand写入文件，而不是在新行上写入ewcommand?

How do I get Python to write \newcommand to a file, instead of writing ewcommand on a new line?

代码是这样的...

with open(fileout,'w',encoding='utf-8') as fout:
    fout.write("\begin{enumerate}[1.]\n")

推荐答案

一种解决方案是转义转义字符(\).这将导致在b字符之前的文字反斜杠，而不是转义b:

One solution is to escape the escape character (\). This will result in a literal backslash before the b character instead of escaping b:

with open(fileout,'w',encoding='utf-8') as fout:
    fout.write("\\begin{enumerate}[1.]\n")

这将被写入文件

\begin{enumerate}[1.]<newline>

(我假设最后的\n是有意的换行符.如果不是，请在此处也使用双转义符:\\n.)

(I assume that the \n at the end is an intentional newline. If not, use double-escaping here as well: \\n.)
