如何在Python中读取多行原始输入？

Question

我想创建一个Python程序，该程序需要多行用户输入。例如：

This is a multilined input.
It has multiple sentences.
Each sentence is on a newline.

如何接收多行原始输入？

Answer 1

sentinel = '' # ends when this string is seen
for line in iter(raw_input, sentinel):
    pass # do things here

要将每一行作为字符串获取，你可以执行以下操作：

'\n'.join(iter(raw_input, sentinel))

Python 3：

'\n'.join(iter(input, sentinel))
