所以我有一个测试字符串
content = 'I opened my mouth, "Good morning!" I said cheerfully'
我想使用正则表达式删除双语音标记之间的文本，但不删除语音标记本身。所以它会回来
'I opened my mouth, "" I said cheerfully'
我正在使用以下代码
content = re.sub(r'".*"'," ",content)
但这也消除了双重语音标记。我应该使用哪种模式来保留语音标记，但删除其中的文本。
使用'""'作为替换字符串：
>>> content = 'I opened my mouth, "Good morning!" I said cheerfully'
>>> content = re.sub(r'".*"', '""', content)
>>> print(content)
I opened my mouth, "" I said cheerfully
顺便说一句，.*尽可能匹配（贪婪）。要匹配非贪婪的方式，请使用.*?或[^"]*。
>>> content = 'I opened my mouth, "Good morning!" I said cheerfully. "How is everyone?"'
>>> content = re.sub(r'".*?"', '""', content)
>>> print(content)
I opened my mouth, "" I said cheerfully. ""
