Python - 分割點是一個單詞數組

Question

我想根據當前存儲在數組中的單詞分割一個句子。數組存儲我想作爲分割點的單詞。我可以使用正則表達式作爲分割點嗎？

例子：

array=['and','also','but'] 

文本文件：

I am new to Python and I need help. I am also asking a question. 

需要的輸出：

I need help 
asking a question 

Answer 1

可以使用re.split()功能：

import re 
array = ['and','also','but'] 
sentence = "I am new to Python and I need help. I am also asking a question." 
result = re.split("|".join(array), sentence) 

我會加裝飾：

result = [x.strip() for x in result] 
print(result) 

Answer 2

這裏是@hurturk解決方案的適應性 - 這將產生@blahhh請求的輸出。
自從上週我的水晶球爆發以來，這個算法是否是@blahhh的意圖，是任何人的猜測。

from __future__ import print_function 

import re 
array = ['and', 'also', 'but'] 
separators = ['\.', '\;', '\?', '\!'] 
sentence = "I am new to Python and I need help. I am also asking a question." 

sentences = re.split("|".join(separators), sentence) 
for sentence in sentences: 
    result = re.split("|".join(array), sentence) 
    result = [x.strip() for x in result] 
    print(result[-1]) 

其中輸出是：

I need help 
asking a question
