def __init__(self, host='', port=None, strict=None):

    # some joker passed 0 explicitly, meaning default port
    if port == 0:
      port = None

    # Note that we may pass an empty string as the host; this will throw
    # an error when we attempt to connect. Presumably, the client code
    # will call connect before then, with a proper host.

Provide a default host, since the superclass requires one.
