我想使用匹配两个字符串之间任何文本的正则表达式：
Part 1. Part 2. Part 3 then more text
在这个例子中，我想搜索＆＃34;第1部分＆＃34;和＆＃34;第3部分＆＃34;然后得到介于两者之间的所有内容：＆＃34;。第2部分。＆＃34;
我正在使用Python 2x。

re.search如果有多个出现，请使用>>> import re
>>> s = 'Part 1. Part 2. Part 3 then more text'
>>> re.search(r'Part 1\.(.*?)Part 3', s).group(1)
' Part 2. '
>>> re.search(r'Part 1(.*?)Part 3', s).group(1)
'. Part 2. '
