Where?
I'm trying google and any of the proxys I've tried worked...
I'm trying urllib.open with it...
I don't know if urllib need some special proxy type or something like that...
Thank you
ps: I need some proxies to ping a certain website and not got banned from my ip
You probably don't even need to use a proxy. The urllib module knows how to contact web servers directly. 
You may need to use a proxy if you're behind certain kinds of corporate firewalls, but in that case you can't just choose any proxy to use, you have to use the corporate proxy. In such a case, a list of open proxies on Google isn't going to help you.
Where can I get some proxy list good for use it with Python?
