在 Python 中用单个空格替换多个空格 [英] Substitute multiple whitespace with single whitespace in Python

问题描述

我有这个字符串:

mystring = 'Here is  some   text   I      wrote   '

如何用一个空格替换双、三 (...) 空格字符，以便得到:

How can I substitute the double, triple (...) whitespace chracters with a single space, so that I get:

mystring = 'Here is some text I wrote'

推荐答案

一个简单的可能性(如果你宁愿避免 REs)是

A simple possibility (if you'd rather avoid REs) is

' '.join(mystring.split())

split 和 join 执行您明确询问的任务——此外，它们还执行您未提及但在您的示例中看到的额外任务，删除尾随空格；-)

The split and join perform the task you're explicitly asking about -- plus, they also do the extra one that you don't talk about but is seen in your example, removing trailing spaces;-).
