# -*- coding: UTF-8 -*-
import urllib

urlp = 'http://translate.google.cn/translate_tts?'
tar = 'd:/'
  
url = urlp + "ie=UTF-8&q=%s&tl=ja&total=1&idx=0&textlen=%s&prev=input"
url = url %(urllib.quote('お口に合いますか'),8)
fn = tar + 'abc' + '.mp3'
print url + ' => ' + fn
#f = open(fn, 'wb')    
urllib.urlretrieve(url, fn)
#f.close()
