怎样移除文本中第一个括号之前和最后一个括号之后的所有字符？

我们可以使用Python的re模块进行正则表达式匹配，选择第一个左括号和最后一个右括号之间的所有字符，将其替换为空字符串。代码示例如下：

import re

text = "This is an example (text) with brackets; please remove (all text before) the first bracket and (all text after) the last bracket."

result = re.sub(r'(?<=\()[^()]+(?=\))', '', text)

print(result)

输出结果为：

This is an example () with brackets; please remove () the first bracket and () the last bracket.
