python, using chat socketserver module concurrency

Use socketserver module is easy to implement concurrent functions, the following server.py client.py and procedures to achieve this functionality.

#server.py
import socketserver
class MyServer(socketserver.BaseRequestHandler):
    def handle(self):
        while True:
            conn = self.request
            while True:
                data = conn.recv(1024)
                if str(data,'utf8') == 'q':
                    break
                print(str(data,'utf8'))
                inp = input('>>>')
                conn.send(bytes(inp,'utf8'))
            conn.close()
if __name__ == '__main__':
    server = socketserver.ThreadingTCPServer(('127.0.0.1',8000),MyServer)
    server.serve_forever()

#client.py
import socket
sk = socket.socket()
address = ('127.0.0.1',8000)
sk.connect(address)
while True:
    inp = input('>>>')
    if inp == 'q':
        print('Bye-bye')
        break
    sk.send(bytes(inp,'utf8'))
    data = sk.recv(1024)
    print(str(data,' Utf8 ' ))
