再版（串） [英] repr(string)
问题描述
我一直在每个字段一行保存数据。
现在有些字段可能会成为多行字符串...
当我意识到repr（）和eval（）应该
时，我正准备开始逃避和无线换行
。因此问题：如果s是一个字符串，那么repr（s）
保证不包含换行符吗？

I''ve been saving data in a file with one line per field.
Now some of the fields may become multi-line strings...
I was about to start escaping and unescaping linefeeds
by hand, when I realized that repr() and eval() should
do. Hence the question: If s is a string, is repr(s)
guaranteed not to contain line breaks?

在引用换行符的意义上？是的，repr就是这样。
In the sense that line breaks are quoted ? Yes, repr does that.

是的。
请记住，对不受信任的数据使用eval（）并不是很好/>
想法。

yes.
just keep in mind that using eval() on untrusted data isn''t a very good
idea.

对。这些数据来自我，被放入一个文件然后
由我读。有人_could_腐败了那个文件，但是那个可以做到这一点的人可以更容易地把机器扔出来
窗口......
Right. This data comes from me, gets put into a file and then
read by me. Someone _could_ corrupt that file, but someone who
could do that could more easily just throw the machine out
the window...
