如何在TXT文件每行开头添加文本并末尾加一行空白行

Question

我有一个文本文件，内容如下：

this is 1 line
this is 2 line
this is 3 line

我想把它转换成下面这样的格式：

\begin{enumerate}
\item this is 1 line
\item this is 2 line
\item this is 3 line
\end{enumerate}

我正在使用下面的代码：

prefix = '\\item '

with open('new.txt', 'r') as src:
    with open('dest.txt', 'w') as dest:
       dest.write("\\begin{enumerate}\n")
       for line in src:
           dest.write('%s%s\n' % (prefix, line.rstrip('\n')))

但是我似乎无法正确地添加最后一行“\end{enumerate}”。有人能帮忙吗？

只需在你的 with 语句的最后加上这一行：

prefix = '\\item '

with open('new.txt', 'r') as src:
    with open('dest.txt', 'w') as dest:
       dest.write("\\begin{enumerate}\n")
       for line in src:
           dest.write('%s%s\n' % (prefix, line.rstrip('\n')))
       dest.write("\\end{enumerate}\n")
