如何从python中的字符串中删除子字符串“-”，但保留“-”子字符串？

Question

示例：

string = " a lot of text ... protective equip- ment ... a lot of text - with similar broken words like simple appli- cations ..."

我需要获得相同的文本，但设备变成设备，而应用程序变成应用程序。谢谢

尝试一下：

>>> import re
>>> string = " a lot of text ... protective equip- ment ... a lot of text - with similar broken words like simple appli- cations ..."
>>> re.sub(r"(\w+)- (\w+)", r"\1\2", string)
' a lot of text ... protective equipment ... a lot of text - with similar broken words like simple applications ...'
