TCP客户端运行出错，TypeError: a bytes-like object is required, not 'str'

Question

from socket import *

HOST = 'localhost'
PORT = 21567
BUFSIZ = 1024
ADDR = (HOST,PORT)

tcpCliSock = socket(AF_INET,SOCK_STREAM)
tcpCliSock.connect(ADDR)

while True:
data = input('>')
if not data:
break
tcpCliSock.send(data)
data = tcpCliSock.recv(BUFSIZ)
if not data:
break
print(data.decode('utf-8'))
tcpCliSock.close()

改程序运行后出现：TypeError: a bytes-like object is required, not 'str' 告警，什么原因？
