#服务端
import socket

sk = socket.socket()
# print(sk)
address = (‘127.0.0.1‘,8000)

sk.bind(address)

sk.listen(3)
print(‘waiting....‘)
conn,addr = sk.accept()
# print(conn,addr)
inp = input(‘>>>‘)
conn.send(bytes(inp,‘utf8‘))




# server下的方法：
# bind()
# listen()
# accept()
# close()
# conn.close() 关闭一个客户的通道
# sk.close() 关闭整个服务端的通道

# recv , send 传送的内容一定要bytes类型
# recv() # 收消息
# send(string) # 发消息
# sendall() # while true send

# client 下的方法
# connect()
# recv() # 收消息
# send(string) # 发消息
# sendall() # while true send
# close()  关闭通道


# 客户端
import socket

sk = socket.socket()
# print(sk)
address = (‘127.0.0.1‘,8000)
sk.connect(address)
date = sk.recv(1024)
print(str(date,‘utf8‘))
sk.close()
