import socket
#1.实例化socket
server=socket.socket()
#2.绑定端口号
server.bind(('localhost',6969))
#3.开启监听
server.listen()
print('等待连接')
#4.等待连接
conn,addr=server.accept()
while True:
    #5.接收数据
    data=conn.recv(1024)
    if data=='':
        break
    print(data.decode())
    #6.发送数据
    conn.send('数据接收成功'.encode())
#7.关闭连接
conn.close()
