python中的多重分割

re.split ()

s = "Wouldn't it be (most) beneficial to have (at least) some idea?"
l = re.split('[()]', s);

在这种特殊情况下,听起来先按空格分割,然后修剪括号更有意义。

out = []
for element in "Wouldn't it be (most) beneficial to have (at least) some idea?".split():
  out.append(element.strip('()'))

Hm.…重新阅读这个问题,你想要保留一些空间,所以也许不是:)但是保持它在这里。

使用正则表达式,两者都匹配 () 字符:

import re
re.split('[()]', string)

可以使用正则表达式的拆分:

import re
pattern = re.compile(r'[()]')
pattern.split("Wouldn't it be (most) beneficial to have (at least) some idea?")
["Wouldn't it be ", 'most', ' beneficial to have ', 'at least', ' some idea?']
