python正则表达式-在re.sub之前删除空格

这是我的代码片段，这是基本的，我知道！我开始进入regex。当我运行下面的程序时，一切都正常，但我想知道如何缩小连字符和字符串替换之间的差距，例如，无论它在哪里表示一天的持续时间，例如，“八小时一天”现在改为“八小时一天”，我想关闭该空间。请帮忙

import re

short_par = 'You must pace your work. What do I mean? I’m glad you asked that. We pace our work according to the eight-hour workday. If you have twelve hours of work in your in-box, for example, you must compress that work into the eight-hour day. If you have one hour of work in your in-box, you must expand that work to fill the eight- hour day. That was a good question. Feel free to ask questions. Ask too many questions, however, and you may be let go.'

regex = re.compile('[hy]our')

print(regex.sub('BOOGIE', short_par))

您可以使用：

---

（？：（？请尊重SO社区并发布最简单的示例。不需要整个长
短\u par
字符串来说明您的问题，但我们必须水平滚动它才能找到
的“八小时”
place。我想你也可以使用
re.sub
做你想做的。你应该能够找到答案。非常有帮助，谢谢大家的见解。
(?:(?<=-) )?[hy]our
