如何在python raw_input（）函数中包含换行符？ [英] How to include a newline in the python raw_input() function?

问题描述

我正在使用 raw_input（）将消息存储在变量中。因此，我无法按Enter键来输入回车符/换行符来开始新的段落。现在，如果我按Enter键，它将继续进行程序的下一部分。

I'm using raw_input() to storing a message inside a variable. So I can't press enter for a carriage return/new line to start a new paragraph. Right now if I press enter it will just proceed to the next portion of my program.

我已经尝试过类似的操作：

I already tried something like this:

>>> message = raw_input("Message: ")
Message: Hello Sir, \n It's great that..
>>> message
"Hello Sir, \\n It's great that.."
>>> 

它没有用，我也尝试用单引号和双引号将其括起来，但也没有

It didn't worked, and I also tried enclosing it in single and double quotes, which also didn't worked.

我知道还有其他方法可以执行此操作，例如使用 wxpython 或 tkinter ，但我想严格控制它。

I understand that there are other ways of doing this, like using wxpython or tkinter, but I want to keep it strictly console. Is this possible?

推荐答案

可以使用 sys 模块吗？如果需要，这可以解决问题。只需按Ctrl-D即可结束。

Can you use the sys module? This will do the trick if you want. Just hit Ctrl-D to end it.

import sys
message = sys.stdin.readlines()

否则，这会回答您的问题： Python raw_input忽略换行符

Otherwise, this answers your question: Python raw_input ignore newline
