提取日期模式的Python正则表达式

我有一个这样的句子（关键字后跟左括号，后跟任意字符串，后跟两个日期，以连字符分隔）：

我需要使用正则表达式从这个句子中提取出生日期（1869年10月2日）和死亡日期（1948年1月30日）。我已经编写了正则表达式来提取日期模式

date_pattern="(\d{1,2}(\s|-|/)?(Jan(uary)?|Feb(ruary)?|Mar(ch)?|Apr(il)?|May?|June?|July?|Aug(ust)?|Sep(t(ember)?)?|Oct(ober)?|Nov(ember)?|Dec(ember)?|\d{1,2})(\s|-|/)?\d{2,4})"

我需要提取上述表格中的句子，并分别打印出生日期和死亡日期

import re
date_pattern="(\d{1,2}(?:\s|-|/)?(?:Jan(?:uary)?|Feb(?:ruary)?|Mar(?:ch)?|Apr(?:il)?|May?|June?|July?|Aug(?:ust)?|Sep(?:t(?:ember)?)?|Oct(?:ober)?|Nov(?:ember)?|Dec(?:ember)?|\d{1,2})(?:\s|-|/)?\d{2,4})"

bio = "Mohandas Karamchand Gandhi (/ˈɡɑːndi, ˈɡæn-/; Hindustani: [ˈmoːɦənd̪aːs ˈkərəmtʃənd̪ ˈɡaːnd̪ʱi]; 2 October 1869 – 30 January 1948) was the preeminent leader of the Indian independence movement in British-ruled India."

matches = re.findall(date_pattern, bio)
if matches and len(matches) > 1:
   born = matches[0]
   died = matches[1]
   print("Born:", born)
   print("Died:", died)

输出：

---

这是一个“为我调试我的代码”类型的问题，还是您正在努力解决的问题的特定部分？日期是多种不同的格式，还是只有一种特定的格式？你必须担心大写和小写吗？你在哪里卡住了，哪里没有解决你的问题？如果输入格式和你问题中的例子一样规则，你根本不需要正则表达式。每个信息都用括号和分号表示，因此您可以使用

str.split

获取部分，然后使用

datetime.strtime

解析日期。嗨，我需要匹配fom:关键字（甘地）的整个句子后跟左括号，后跟任意字符串，后跟2个日期，以连字符分隔，然后提取日期。这是一个例句。这句话中可能有许多其他日期。所以我需要提取满足上述条件的句子，然后提取出生和死亡日期，关键字后面跟左括号，后面跟任意字符串，后面跟两个用连字符分隔的日期

import re
date_pattern="(\d{1,2}(?:\s|-|/)?(?:Jan(?:uary)?|Feb(?:ruary)?|Mar(?:ch)?|Apr(?:il)?|May?|June?|July?|Aug(?:ust)?|Sep(?:t(?:ember)?)?|Oct(?:ober)?|Nov(?:ember)?|Dec(?:ember)?|\d{1,2})(?:\s|-|/)?\d{2,4})"

bio = "Mohandas Karamchand Gandhi (/ˈɡɑːndi, ˈɡæn-/; Hindustani: [ˈmoːɦənd̪aːs ˈkərəmtʃənd̪ ˈɡaːnd̪ʱi]; 2 October 1869 – 30 January 1948) was the preeminent leader of the Indian independence movement in British-ruled India."

matches = re.findall(date_pattern, bio)
if matches and len(matches) > 1:
   born = matches[0]
   died = matches[1]
   print("Born:", born)
   print("Died:", died)

import re

text = '''Mohandas Karamchand Gandhi (/ˈɡɑːndi, ˈɡæn-/; Hindustani: [ˈmoːɦənd̪aːs ˈkərəmtʃənd̪ ˈɡaːnd̪ʱi]; 2 October 1869 – 30 January 1948) was the preeminent leader of the Indian independence movement in British-ruled India.'''
birth, death = re.findall(r'\d+[ \d\w]+', text)
print(birth)
print(death)

2 October 1869 
30 January 1948
