How to set up a proxy for Python urllib

In this article, we'll explore how to set up a proxy for Python3 urllib, a built-in library used for making HTTP requests. We'll provide a code snippet that demonstrates how to define a proxy server and port number, create a ProxyHandler object, and use it to make requests through the proxy.

To set up a proxy for Python3 urllib, you can use the urllib.request.ProxyHandler class to define the proxy server and port number, and then use this object to create an opener object which will be used to make requests through the proxy.

Here is an example code snippet that shows how to set up a proxy using urllib:

from urllib import request

# Define the proxy server and port number
proxy_server = 'http://yourproxyserver.com'
proxy_port = '8080'

# Create a ProxyHandler object with the proxy server and port
proxy_handler = request.ProxyHandler(
    {
        'http': f'{proxy_server}:{proxy_port}',
        'https': f'{proxy_server}:{proxy_port}'
    }
)

# Create an opener object with the ProxyHandler
opener = request.build_opener(proxy_handler)

# Use the opener to make a request through the proxy
response = opener.open('http://example.com')

# Print the response
print(response.read())

In this example, replace http://yourproxyserver.com with the URL of your proxy server, and 8080 with the port number your proxy server is using. Then replace http://example.com with the URL of the website you want to access through the proxy.
