How to use the rs4.asynchat.async_chat.__init__ function in rs4

def __init__ (self, conn, addr):
			self.addr = addr
			asynchat.async_chat.__init__ (self, conn)
			self.set_terminator (b'\r\n')
			self.buffer = ''
			self.count = 0

def __init__ (self, addr, logger):
        self.addr = addr
        self.logger = logger                
        self.event_time = time.time ()
        self.creation_time = time.time ()        
        self.closed = False
        self._timeouted = False
        self.requests = {}
        self.callback = None
        asynchat.async_chat.__init__ (self)

def __init__ (self, address, params = None, lock = None, logger = None):
		dbconnect.AsynDBConnect.__init__ (self, address, params, lock, logger)
		asynchat.async_chat.__init__ (self)
