如何使正則表達式一行一行地匹配兩個字符串？

Question

這個問題措辭有點怪異，但我不知道該怎么問。

我正在使用wordnet提取一些定義，我需要讓正則表達式從輸出中提取詞性和定義，如下所示：如果我查找單詞study

Overview of verb study

1. reading, blah, blah (to read a book with the intent of learning)
2. blah blah blah (second definition of study)

Overview of noun study

1. blah blah blah (the object of ones study)
2. yadda yadda yadda (second definition of study)

我想讓這個退貨...

[('verb', 'to read a book with the intent of learning'), ('verb', 'second definition of study'), ('noun', 'the object of ones studying'), ('noun','second definition of study')]

我有兩個與我想要的正則表達式匹配的表達式，但是我無法弄清楚如何遍歷數據才能最終獲得所需的數據結構。 有任何想法嗎？

編輯：

添加正則表達式模式

stripped_defs = re.findall('^\s*\d+\..*\(([^)"]+)', definitions, re.M)
pos = re.findall('Overview of (\w+)', definitions)

Answer 1

我的方式是（ text就是文字）：

1. 通過Overview of...將它們拆分：

    >>> re.split('Overview of (\\w+) study', text)[1:] ['verb', '\\n\\n1. reading, blah, blah (to read a book with the intent of learning)\\n2. blah blah blah (second definition of study)\\n\\n', 'noun', '\\n\\n1. blah blah blah (the object of ones study)\\n2. yadda yadda yadda (second definition of study)'] >>> l = re.split('Overview of (\\w+) study', text)[1:] 

2. 像這樣拆分列表：

    >>> [l[i:i+2] for i in range(0, len(l), 2)] [['verb', '\\n\\n1. reading, blah, blah (to read a book with the intent of learning)\\n2. blah blah blah (second definition of study)\\n\\n'], ['noun', '\\n\\n1. blah blah blah (the object of ones study)\\n2. yadda yadda yadda (second definition of study)']] >>> l = [l[i:i+2] for i in range(0, len(l), 2)] 

然后我們可以簡單地做：

>>> [[(i, k) for k in re.findall('\((.+?)\)', j)] for i, j in l]
[[('verb', 'to read a book with the intent of learning'),
  ('verb', 'second definition of study')],

 [('noun', 'the object of ones study'),
  ('noun', 'second definition of study')]]

得到您期望的輸出：

final_list = []
for i in [[(i, k) for k in re.findall('\(.+?\)', j)] for i, j in l]:
    final_list.extend(i)

print(final_list)

這使：

[('verb', 'to read a book with the intent of learning'),
 ('verb', 'second definition of study'),

 ('noun', 'the object of ones study'),
 ('noun', 'second definition of study')]

---

碼：

l = re.split('Overview of (\w+) study', text)[1:]
l = [l[i:i+2] for i in range(0, len(l), 2)]

# or just `final_list = l` if it doesn't matter
final_list = []

for i in [[(i, k) for k in re.findall('\(.+?\)', j)] for i, j in l]:
    final_list.extend(i)
