Send Twitter update using Python

Well I've been reading this book called "head first beginning programming" so I can learn Python without all the bloat of normal Python books. I modified a function that they used to accept your username and password as parameters. I might add string length checking to so that you dont get errors for the message being to long.

Code:

# includes start

import urllib.request

#includes end

def sendTwitterUpdate(msg,twitUserName,twitPassword):
    passManager = urllib.request.HTTPPasswordMgr()
    passManager.add_password("Twitter API","http://twitter.com/statuses",twitUserName,twitPassword)
    httpHandle = urllib.request.HTTPBasicAuthHandler(passManager)
    pageOpener = urllib.request.build_opener(httpHandle)
    urllib.request.install_opener(pageOpener)
    params = urllib.parse.urlencode({'status': msg})
    response = urllib.request.urlopen("http://twitter.com/statuses/update.json", params)
    response.read()
