How to Use Proxies to Rotate IP Addresses in Python

To use proxies to rotate IP addresses in Python, you can use the requests library along with a list of proxies. Here is an example code that shows how to send an HTTP GET request using a rotating proxy:

import requests
from itertools import cycle

# define the list of proxies
proxies = [
    'http://proxy1.com:1234',
    'http://proxy2.com:2345',
    'http://proxy3.com:3456'
]

# create an iterator that will loop over the proxies
proxy_pool = cycle(proxies)

url = 'https://www.example.com/'

# send GET requests using rotating proxies
for i in range(3):
    # get the next proxy from the proxy pool
    proxy = next(proxy_pool)
    print(f"Using proxy {proxy}")

    try:
        response = requests.get(url, proxies={'http': proxy, 'https': proxy}, timeout=5.0)
        print(response.status_code)
        print(response.content)
    except Exception as e:
        print(e)

In this example, we have defined a list of proxies with their respective URLs. We then create an iterator called proxy_pool that will loop over the proxies indefinitely using the cycle() function imported from itertools.

We then send GET requests to a target URL using the requests.get() method, and we pass a dictionary of proxies along with the request using the proxies parameter. The timeout parameter is set to 5.0 to avoid waiting indefinitely for a response.

We then use a try-except block to catch any exceptions that may arise from sending the requests, such as connection timeouts or invalid proxies.
