Python -- 网络编程socket(1)

server端

import socket
sk = socket.socket()
address = ('127.0.0.1',8000)
sk.bind(address)
sk.listen(3)    #这里的3是指允许等待连接的数量
print('waitting......')
conn,addr = sk.accept()
input01 = input('发送>>>')
conn.send(bytes(input01,'utf-8'))
data1=conn.recv(1024)
print(str(data1,'utf-8'))

client端

import socket
sk = socket.socket()    #建立tcp连接
address = ('127.0.0.1',8000)
sk.connect(address)
data=sk.recv(1024)    #1024为最大接收数据量，k
print(str(data,'utf-8'))
data1=sk.send(bytes('一二三','utf-8'))
