改成这样：

1. from requests import get
   
2. import re
   
3. 
   
4. def open_url(url):
   
5.     headers = {'User-Agent':'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.97 Safari/537.36'}
   
6.     html = get(url, headers = headers)
   
7.     html.encoding = html.apparent_encoding
   
8. 
   
9.     return html.text
   
10. 
    
11. def get_img(html):
    
12.     p=r'<img alt="赵丽颖" src="[^"]+\.jpg"'
    
13.     imglist=re.findall(p,html)
    
14. 
    
15.     for each in imglist:
    
16.         print(each)
    
17. 
    
18. if __name__=='__main__':
    
19.     url="http://www.ik123.com/q/tuku/fzl/61045.html"
