Python中的多重分割

Question

如何將兩個相反的值分割爲一個字符串？例如(和)是 「deliminators」 和我有以下字符串：

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

我需要以下輸出（作爲數組）

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

Answer 1

re.split（）

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

Answer 2

您可以使用正則表達式的分割：

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?'] 

Answer 3

使用正則表達式，既()字符匹配：

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

Answer 4

在這種特殊情況下，聽起來就像將通過空間更有意義，先分割，然後修剪括號。

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

嗯...重讀這個問題，你想保留一些空間，所以也許不是:)，但仍然保持在這裏。
