在空格或连字符上分开? [英] Split on either a space or a hyphen?

问题描述

在Python中，如何在空格或连字符之间分割?

In Python, how do I split on either a space or a hyphen?

输入:

You think we did this un-thinkingly?

所需的输出:

["You", "think", "we", "did", "this", "un", "thinkingly"]

我可以做到

mystr.split(' ')

但是我不知道如何分割连字符和空格 Python的split定义似乎只指定了一个字符串.我需要使用正则表达式吗?

But I don't know how to split on hyphens as well as spaces and the Python definition of split only seems to specify a string. Do I need to use a regex?

推荐答案

如果您的模式对于一个(或两个)replace足够简单，请使用它:

If your pattern is simple enough for one (or maybe two) replace, use it:

mystr.replace('-', ' ').split(' ')

否则，请按照 @jamylak 的建议使用RE.

Otherwise, use RE as suggested by @jamylak.
