python爬取i春秋文章标题

最近自学python爬虫入门，好奇想尝试一下

环境：python3.8
目标：i春秋的视频文章标题

代码如下

import requests
import re
 
def getTitle():
    url = 'https://bbs.ichunqiu.com/portal.php'
    headers = {
            'Host': 'bbs.ichunqiu.com',
            'Connection': 'close',
            'Cache-Control': 'max-age=0',
            'Upgrade-Insecure-Requests': '1',
            'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36',
            'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8',
            'Accept-Language': 'zh-CN,zh;q=0.8',
            }
    req = requests.get(url=url,headers=headers)
    html = req.content
    titlere = r'target="blank" class="ui_colorG" style="color: #555555;">(.+?)</a></h3>'
    title = re.findall(titlere,html.decode('utf-8'))
    num=0
    for titles in title:
        num=num+1
        print (num,titles)
if __name__ == '__main__':
    getTitle()

结果显示
