python - 使用正则表达式从文本文件中提取字符串

Question

基本上我有一个 txt 文档，里面有这个，

The sound of a horse at a gallop came fast and furiously up the hill.
"So-ho!" the guard sang out, as loud as he could roar.
"Yo there! Stand! I shall fire!"
The pace was suddenly checked, and, with much splashing and floundering, a man's voice called from the mist, "Is that the Dover mail?"
"Never you mind what it is!" the guard retorted. "What are you?"
"_Is_ that the Dover mail?"
"Why do you want to know?"
"I want a passenger, if it is."
"What passenger?"
"Mr. Jarvis Lorry."
Our booked passenger showed in a moment that it was his name.
The guard, the coachman, and the two other passengers eyed him distrustfully.

使用正则表达式我需要在双引号内打印所有内容，我不想要完整的代码我只需要知道我应该如何去做，哪个正则表达式最有用。请提示和指点!

Answer 1

r'(".*?")' 将匹配双引号内的每个字符串。括号表示捕获的组，. 匹配每个字符(换行符除外)，* 表示重复，? 表示重复非贪婪(在下一个双引号之前停止匹配)。如果需要，请包含 re.DOTALL 选项以使 . 也匹配换行符。
