As the socket.connect docs says, AF_INET6 expects a 4-tuple:

sockaddr is a tuple describing a socket address, whose format depends on the returned family (a (address, port) 2-tuple for AF_INET, a (address, port, flow info, scope id) 4-tuple for AF_INET6), and is meant to be passed to the socket.connect() method.

For example:

>>> socket.getaddrinfo("www.python.org", 80, 0, 0, socket.SOL_TCP)
[(2, 1, 6, '', ('82.94.164.162', 80)),
 (10, 1, 6, '', ('2001:888:2000:d::a2', 80, 0, 0))]

>>> ourSocket = socket.socket(socket.AF_INET6, socket.SOCK_STREAM, 0)
>>> ourSocket.connect(('2001:888:2000:d::a2', 80, 0, 0))
