docs: Connect to *address* and return the socket object.
  
      Convenience function.  Connect to *address* (a 2-tuple ``(host,
      port)``) and return the socket object.  Passing the optional
      *timeout* parameter will set the timeout on the socket instance
      before attempting to connect.  If no *timeout* is supplied, the
      global default timeout setting returned by :func:`getdefaulttimeout`
      is used.  If *source_address* is set it must be a tuple of (host, port)
      for the socket to bind as a source address before making the connection.
      An host of '' or port 0 tells the OS to use the default.
