python如何将带有"../"的网址还原成真实路径？

最近写程序遇到了些问题，做短网址的时候会遇到

http://url.com/upload/img/2012/08/../../xxxx

这样的网址，想将这些相对路径还原成绝对路径，来保证数据的唯一性，应该转换成下面这样吧

http://url.com/upload/img/xxxx

python 下有没有相应的方法或者相关的包呢？

import os
import urlparse

URL = "http://url.com/upload/img/2012/08/../../xxxx"

u = urlparse.urlparse(URL)
print os.path.realpath(u.path)
