requests 模块例题示范

requests 模块

re模块和requests模块结合示范实例

.*? 不加圆括号表示在要匹配里面的内容不要；

（.*?）表示在要匹配的两者之间的内容都要；

import requests

import re
content_list=[]
response = requests.get('https://ishuo.cn/')
data=response.text
# print(data)
res=re.findall('<div class="content">(.*?)</div>',data)
res1=re.findall('</span><a href="/subject/.*?">(.*?)</a>',data)
# print(res1)
for i in res:
    if i.startswith('<ul>'):
        continue
    content_list.append(i)
with open(r'duanzi.txt','w',encoding='utf8')as f:
    for j in range(len(content_list)):
        res2=str(f'\n{j}>>>{res1[j]}:\n {content_list[j]}\n')
        # print(res2)
        f.write(res2)
        f.flush()
