import socket
sk = socket.socket()
address = (‘127.0.0.1‘,8000)
sk.bind(address)

sk.listen(3)#等待数

print(‘waiting ..............‘)
# conn = sk.accept()
# print(conn)
#conn客户端
#不能发空，发空的话就直接阻塞
# conn,addr = sk.accept()
# while True:
#     data = conn.recv(1024)
#     print(‘.............‘, str(data, ‘utf8‘))
#     if not data:
#         conn, addr = sk.accept()
#         print(addr)
#         continue
#或者
while 1:
    conn,addr = sk.accept()
    print(addr)
    while 1:
        data = conn.recv(1024)
        print(‘..........‘,str(data,‘utf8‘))
        if not data:break
        inp = input(‘>>>>‘)
        conn.send(bytes(inp,‘utf8‘))




    # inp = input(‘>>>>‘)
    # conn.send(bytes(inp,‘utf8‘))

conn.close()
sk.close()

这是server端代码

import socket

sk = socket.socket()
print(sk)

address = (‘127.0.0.1‘,8000)
sk.connect(address)

while True:
    inp = input(‘>>>>>‘)
    if inp == ‘exit‘:
        break
    sk.send(bytes(inp,‘utf8‘))
    data = sk.recv(1024)
    print(str(data,‘utf8‘))

sk.close()
print(sk)

　　这是Client端代码

首先运行server端
