BUG:

run : urlparse.urlparse('http://google.com]')
then: raise ValueError("Invalid IPv6 URL")

=====================================================
SOURCE:

    if url[:2] == '//':

        netloc, url = _splitnetloc(url, 2)

        if (('[' in netloc and ']' not in netloc) or

                (']' in netloc and '[' not in netloc)):

            raise ValueError("Invalid IPv6 URL")

=====================================================
SOLUTION:

I THINK IT IS BETTER TO JUST REMOVE THE LAST 3 LINES ABOVE
