Whois not working

[mariolopes]

Hi
I want to get various informations about one web site (how old he is etc...). I'm using PyCharm and the following code:

import whois
domain = whois.query('mariolopes.com')

The code is from the page https://pypi.python.org/pypi/whois/0.6.4
Got severeal errors:

Error:

Traceback (most recent call last):

    startupinfo)

Any help, please?
