fetch a html page via proxy?

[Ricardo Jamin]

I need to fetch a page from the web but the linux machine doesn't have
direct connection to the net.  It needs to go thru a proxy to connect
to the web.  How can I do this with Python?  I know how to write
Python code that fetch the page directly, but I can't find any
information about the proxy part.  

thanks in advance.
