Python中的多重分割

Question

我想知道怎么把一个字符串按照两个相对的符号来分割？比如说 ( 和 ) 是“分隔符”，我有一个这样的字符串：

Wouldn't it be (most) beneficial to have (at least) some idea?

我需要得到这样的输出（以数组的形式）

["Wouldn't it be ", "most", " beneficial to have ", "at least", " some idea?"]

Answer 1

使用正则表达式来匹配两个()字符：

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

Answer 2

在这个特定的情况下，听起来先按空格分开，然后再去掉括号会更合理。

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

嗯……再读一遍问题，你想保留一些空格，所以可能不太适合这样做 :) 不过我还是把这个想法保留在这里。

Answer 3

re.split()

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