how does python socketserver pass a variable outside？

I'm using socketserver to make a udpserver, like this:

class UdpServer(socketserver.BaseRequestHandler):      global signal_msg      signal_msg=pyqtSignal(str)      def handle(self):          data =self.request[0]          signal_msg.emit(data.decode('utf-8'))
