以下是使用Python的requests库设置HTTP代理IP的示例代码：

```python

import requests

proxy = {

'http': 'http://your_proxy_ip:your_proxy_port',

'https': 'http://your_proxy_ip:your_proxy_port'

}

response = requests.get('Example Domain', proxies=proxy)

print(response.text)

```

其中，`your_proxy_ip`和`your_proxy_port`分别为你的HTTP代理IP和端口号。将其替换为你自己的代理IP和端口号即可。如果你的代理IP需要用户名和密码认证，可以在`proxy`字典中添加`'http': 'http://username:password@your_proxy_ip:your_proxy_port'`和`'https': 'http://username:password@your_proxy_ip:your_proxy_port'`两个键值对，将`username`和`password`替换为你的代理用户名和密码。
