set the http_proxy environment variable to point to your
proxy server.  e.g:

    import os, urllib

    os.environ["http_proxy"] = http://proxy.spam.egg:1234"

    # connect to www.python.org through proxy.spam.egg:1234
    fp = urllib.urlopen("http://www.python.org")

if you prefer, you can of course set the environment
variable outside your program (using the usual shell
commands).
