正则表达式捕获 2 个引号之间的部分

Question

在尝试捕捉引号之间的短语时，我似乎无法正确使用正则表达式。例如。粗体（注意：输入前后都有字符串）：

“我很能理解你的想法。” 我说。“当然，在 你对每个人的非正式顾问和助手的地位 绝对不解，横跨三大洲，你被带进来 接触一切陌生而离奇的事物。但是这里”

“当然，在你的非官方顾问和助手的位置上， 整个三个大陆，每个完全不解的人，你 接触到所有奇怪和离奇的事物。但 这里”--我从地上捡起晨报--“让我们把 进行实际测试。这是我来的第一个标题。 “丈夫对妻子的残忍。”有半栏印刷， 但我不读就知道这一切对我来说都是非常熟悉的。 当然，还有另一个女人，喝酒，推搡，打击， 瘀伤，同情的姐姐或女房东。最粗鲁的作家 没有比这更粗鲁的发明了。”

我尝试获取引号前后的文本，但无法获得所需的输出。必须有某种方法将正则表达式组合起来，以便 我可以捕获引号之间的字符串以及周围的两个引号。

import re

def get_quotes(paragraph):
    quote_rx = r'''([""])(?:(?=(\\?))\2.)*?\1'''
    return [i.group(0) for i in \
           re.finditer(quote_rx, paragraph, re.S)]

def get_said(paragraph, quote):
    quote_start = paragraph.index(quote)
    quote_end = quote_start + len(quote)
    before = paragraph[:quote_start]
    after = paragraph[quote_end:]
    return before, after

'''Such was the remarkable narrative to which I listened on that April evening -- a narrative which would have been utterly incredible to me had it not been confirmed by the actual sight of the tall, spare figure and the keen, eager face, which I had never thought to see again. In some manner he had learned of my own sad bereavement, and his sympathy was shown in his manner rather than in his words. "Work is the best antidote to sorrow, my dear Watson," said he, "and I have a piece of work for us both to-night which, if we can bring it to a successful conclusion, will in itself justify a man's life on this planet." In vain I begged him to tell me more. "You will hear and see enough before morning," he answered. "We have three years of the past to discuss. Let that suffice until half-past nine, when we start upon the notable adventure of the empty house."''']

for p in paragraphs:
    saids = set()
    for i in get_quotes(p):
        b,a = get_said(p,i)
        print b
        print a
        print

很简单，你需要的正则表达式是r'^("[^"]+")([^"]+)("[^"]+")':

import re

s = """
"I can quite understand your thinking so." I said. "Of course, in your position of unofficial adviser and helper to everybody who is absolutely puzzled, throughout three continents, you are brought in contact with all that is strange and bizarre. But here"

"Of course, in your position of unofficial adviser and helper to everybody who is absolutely puzzled, throughout three continents, you are brought in contact with all that is strange and bizarre. But here"--I picked up the morning paper from the ground--"let us put it to a practical test. Here is the first heading upon which I come. 'A husband's cruelty to his wife.' There is half a column of print, but I know without reading it that it is all perfectly familiar to me. There is, of course, the other woman, the drink, the push, the blow, the bruise, the sympathetic sister or landlady. The crudest of writers could invent nothing more crude."
"""

for segment in s.splitlines():
    if not segment:
        continue
    first, said, second = re.match(r'^("[^"]+")([^"]+)("[^"]+")', segment).groups()
    print first
    print said
    print second

>>> 
"I can quite understand your thinking so."
