Python - Google translator (pytranslator)

While working on internationalization (i18n), I had to translate a whole bunch of text statements from English to German! I didn't wanted to access http://google.com/translate in the browser for every text to be translated and do the routine copy paste. So I decided to write a python program which translates text across google support translation languages. Its a python module that one can import and use it based on their needs. For example to translate an entire GNU portable object file(.po) from one language to another.
I call it the "pytranslator"

import sys
import urlib
import re

langCode={ "arabic":"ar", "bulgarian":"bg", "chinese":"zh-CN", "croatian":"hr", "czech":"cs", "danish":"da", "dutch":"nl", "english":"en", "finnish":"fi", "french":"fr", "german":"de", "greek":"el", "hindi":"hi", "italian":"it", "japanese":"ja", "korean":"ko", "norwegian":"no", "polish":"pl", "portugese":"pt", "romanian":"ro", "russian":"ru", "spanish":"es", "swedish":"sv" }

def setUserAgent(userAgent):
    urllib.FancyURLopener.version = userAgent
    pass

def translate(text, fromLang="English", toLang="German"):
    # urllib.FancyURLopener.version = "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.1) Gecko/2008070400 SUSE/3.0.1-0.1 Firefox/3.0.1"
    setUserAgent("Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.1) Gecko/2008070400 SUSE/3.0.1-0.1 Firefox/3.0.1")
    try:
        post_params = urllib.urlencode({"langpair":"%s|%s" %(langCode[fromLang.lower()],langCode[toLang.lower()]), "text":text,"ie":"UTF8", "oe":"UTF8"})
    except KeyError, error:
        print "Currently we do not support %s" %(error.args[0])
        return
    page = urllib.urlopen("http://translate.google.com/translate_t", post_params)
    content = page.read()
    page.close()
    match = re.search("<div id=result_box dir=\"ltr\">(.*?)</div>", content)
    value = match.groups()[0]
    return value
