import socket

sk = socket.socket()
address = ('127.0.0.1', 9000)
sk.bind(address)
sk.listen(3)
print('waitting......')

while True:
    conn, addr = sk.accept()
    print('新來一個',addr)
    while True:
        data = conn.recv(1024)
        if not data:
            print('關閉了一個連結')
            conn.close()
            break
        print(str(data, 'utf8'))
        inp = input('>>>>')
        conn.send(bytes(inp, 'utf8'))
 

第二部分客戶端

# Author:qintao_xu
# date:2018/10/6
import  socket

sk = socket.socket()
address = ('127.0.0.1', 9000)
sk.connect(address)
while True:
    inp = input('>>>>')
    if inp == 'exit':
        break
    sk.send(bytes(inp, 'utf8'))
    data = sk.recv(1024)
    print(str(data, 'utf8'))
else:
    sk.close()
 

我是本地測試使用的 所以都是127.0.0.1
