为什么opener.addheaders报错？(已解决，不用进来了，删了吧。。）

azzzzzz

1. import urllib.request
   
2. 
   
3. 
   
4. url = "http://www.ip111.cn/"
   
5. 
   
6. proxy_support = urllib.request.ProxyHandler({"http":"117.88.176.252:3000"})
   
7. 
   
8. headers = ("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.149 Safari/537.36")
   
9. opener = urllib.request.build_opener(proxy_support)
   
10. opener.addheaders[headers]
    
11. 
    
12. urllib.request.install_opener(opener)
    
13. 
    
14. response = urllib.request.urlopen(url)
    
15. 
    
16. html = response.read().decode("utf-8")
    
17. 
    
18. print(html)
    

复制代码

报错信息：
Traceback (most recent call last):
  File "D:\python 3.8\资料\爬虫学习\proxy_eg.py", line 10, in <module>
    opener.addheaders[headers]
TypeError: list indices must be integers or slices, not tuple

按照小甲鱼教程这样写报错，网上找了很多都是这样写的，找手册上面找不到这个方法，不知道怎么回事求大佬解答！
