# 不保留分隔符 #

"\[ \]"在里面填写分隔符，不会保留分隔符。

import re
    
    sentence = "你在北京 我,你是谁?在干嘛."
    
    items = re.split("[.。!！?？；;，,\s+]", sentence.decode("utf8"))
    for item in items:
        print item

**结果：**  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3p6enpsZWkxMjMxMjMxMjM_size_16_color_FFFFFF_t_70]

# 保留分割符 #

想要保留分隔符，需要加入（），就是"(\[ \])" 这样就会保留分隔符

import re
    
    sentence = "你在北京 我,你是谁?在干嘛."
    
    items = re.split("([.。!！?？；;，,\s+])", sentence.decode("utf8"))
    for item in items:
        print item

**结果：**  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3p6enpsZWkxMjMxMjMxMjM_size_16_color_FFFFFF_t_70 1]

# 将分隔符放在句子后面 #

这其实是围魏救赵，侧面的解决了问题

import re
    
    a = "你在北京 我,你是谁？在干嘛."
    
    sentences = re.split(r"([.。!！?？；;，,\s+])", a)
    sentences.append("")
    sentences = ["".join(i) for i in zip(sentences[0::2], sentences[1::2])]
    
    print(sentences)

**结果：**

\['你在北京 ', ‘我,’, ‘你是谁？’, ‘在干嘛.’\]
