Web scraping is fun—until you get blocked. But don’t worry! That’s where rotating proxies come in. They help you stay online and scrape like a champ.
In this article, we’ll talk about using rotating proxies with the Python requests
library. It’s easier than you might think. And we’ll give you some handy snippets to get started fast.
🤔 Why Rotate Proxies?
When you send too many requests from one IP address, websites get suspicious. They might:
- Block your IP
- Show CAPTCHA
- Feed you fake data
Rotating proxies swap your IP with each request. This makes it look like the traffic is coming from many users instead of just one. Smart, right?

Before you begin, make sure you have:
- Python installed
- The
requests
library - A list of proxies (free or paid)
You can install requests
like this:
pip install requests
🚀 Rotating Proxies the Easy Way
Here’s a basic way to rotate proxies using a list.
import requests
import random
proxies = [
'http://12.34.56.78:8080',
'http://23.45.67.89:3128',
'http://34.56.78.90:8000'
]
urls = [
'https://example.com/page1',
'https://example.com/page2',
'https://example.com/page3'
]
headers = {
'User-Agent': 'Mozilla/5.0'
}
for url in urls:
proxy = random.choice(proxies)
print(f'Using proxy: {proxy}')
try:
response = requests.get(url, proxies={'http': proxy, 'https': proxy}, headers=headers, timeout=5)
print(f'Status code: {response.status_code}')
except Exception as e:
print(f'Request failed: {e}')
What’s happening here? We loop through URLs and pick a new proxy every time. This keeps your IP looking fresh and less spammy.
👮 Avoid Getting Blocked
Just rotating IPs isn’t always enough. Here are a few extra tricks:
- Use headers: Always include a realistic
User-Agent
. - Obey robots.txt: Be nice to the sites you scrape.
- Slow it down: Add delays between requests to look human.
import time
time.sleep(random.uniform(1, 3)) # Sleep between 1 and 3 seconds
Slowing it down keeps you from setting off alarms. It’s like putting on a fake mustache—only slower.
🔁 Using a Proxy Rotation Service
If you want to level up, try a proxy service like:
- ScraperAPI
- Bright Data
- Smartproxy
These services manage the rotating for you. Just send a request, and voilà!
response = requests.get(
'https://example.com',
proxies={'http': 'http://user:pass@proxyservice.com:8000',
'https': 'http://user:pass@proxyservice.com:8000'}
)

Want to see if your proxy is working? Hit this IP-checker:
response = requests.get('https://httpbin.org/ip', proxies={'http': proxy, 'https': proxy})
print(response.json())
This will show the IP for your current session. If it’s different each time—success!
🎯 Final Thoughts
Rotating proxies can be your secret weapon for reliable scraping. With a few lines of code, you avoid bans, get better data, and have more fun.
Remember: Always respect websites and follow their rules.
Happy scraping!
