How to Use a Proxy with Python Requests? A Step-by-Step Guide or Best Practices for Setting Up a Pyth

"Why Isn't My Python Requests Proxy Working? Common Fixes"

Hey folks! Struggling with your python requests proxy setup? Yeah, been there. Sometimes it just *refuses* to work, and it’s super frustrating.

First, double-check your proxy format—it should be like `http://user:pass@ip:port` or `{"http": "http://ip:port", "https": "https://ip:port"}`. Miss a slash or typo the schema? Boom, broken.

Also, make sure your proxy *actually* works. Test it with a simple `requests.get("http://example.com", proxies=your_proxy)`—if it times out, the proxy might be dead or blocking you.

Oh, and if you’re behind a corp network or VPN, that can mess with your python requests proxy too. Try disabling it temporarily.

Lastly, some sites block known proxy IPs. Rotate or use residential proxies if you’re scraping.

Any other weird issues? Drop ‘em below!

Hey! Had the same issue last week. Turns out my proxy provider was throttling requests.

If you're using free proxies, they're often overloaded or blacklisted. Try a paid service like Luminati or Smartproxy—way more reliable for python requests proxy setups.

Also, check if your script has retries? Sometimes a quick `time.sleep(1)` between calls helps.

Man, proxies can be such a pain. One thing that got me: if you're on Windows, your system proxy settings might override your python requests proxy config.

Run this to check:
```python
import os
print(os.environ.get('HTTP_PROXY'))
```
If it prints something, your env vars are messing with it.

Proxies failing? Ugh.

Quick tip: if you're using `requests.get()`, make sure you're not mixing http/https in your proxy dict. Like, if the site is HTTPS but your proxy only has `"http"` defined, it'll fail silently.

Found this the hard way after 3 hours of debugging.

Yo! Had this exact issue. Two things:

1. Some proxies need auth even if they claim they don't. Try adding dummy creds like `http://user:pass@proxyip:port`—weirdly worked for me once.
2. If you're on a Mac, firewall settings can block python requests proxy traffic. Check `pfctl` rules.

Hey all! OP here.

Tried a bunch of these—turns out my proxy was dead (RIP). Switched to a new one from ProxyNova’s free list and it’s working now.

Still getting SSL errors sometimes though. Is `verify=False` really the only fix? Feels sketchy.

Fun fact: if your proxy uses SSL interception (common in corps), python requests proxy will fail unless you disable cert verification.

Not ideal, but this works in a pinch:
```python
requests.get(url, proxies=proxy, verify=False)
```
Just don't use it for sensitive stuff!

PSA: if you're scraping, rotate your user-agent too! Some sites block proxy traffic with default python-requests headers.

Try this:
```python
headers = {'User-Agent': 'Mozilla/5.0'}
requests.get(url, proxies=proxy, headers=headers)
```
Might save you a headache.
