Python:句子分割会产生一个空格

Question

所以我有一些句子，比如：

The window is over there. The lamp is on. The fire is burning.

当我使用split('.')拆分它时然后用换行符连接它，它就失去了".“

然后我尝试了像(?<=\.)\s这样的正则表达式，但它在第二个和第三个字母的第一个字母之前产生了一个空格：

The window is over there.
 The lamp is on.
 The fire is burning.

我不想要额外的空间。我想要：

The window is over there.
The lamp is on.
The fire is burning.

谢谢

Answer 1

".\n".join(i.strip() for i in a.split("."))

Answer 2

>>> test = "The window is over there. The lamp is on. The fire is burning."
>>> print test.replace(". ",".\n")
The window is over there.
The lamp is on.
The fire is burning.

Answer 3

显然没有处理特殊情况(即句点后没有空格)，为什么不直接处理：

>>> s = 'The window is over there. The lamp is on. The fire is burning.'
>>> print s.replace('. ', '.\n')
The window is over there.
The lamp is on.
The fire is burning.
