Python uses TCP to implement simple conversations

Note : You need to start the server first, before starting the client

TCP server

import socket
from os.path import commonprefix

words = {
    
    
    'how are you?':"Fine thank you",
    'how old are you?':'38',
    'what is your name?':'Ji Ruan',
    "what's your name?":"Ji Ruan",
    'where do you work?':'Nan Yang',
    'bey':'Bye'
}
HOST = ''
PORT = 50007
s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
#绑定socket
s.bind((HOST,PORT))
#开始监听一个客户端连接
s.listen(1)
print("Linsten on port :" ,PORT)
#阻塞等待客户端连接
conn,addr = s.accept()
print("Connected by",addr)
#开始聊天
while True:
    data = conn.recv(512).decode()#解码
    if not data:
        break
    print("Received message:",data)
    # 尽量猜测对方要表达的真正意思
    m = 0
    key = ''
    for k in words.keys():
        #删除多余的空白字符
        data = ' '.join(data.split())
        # 与某个 键接近，就直接返回
        if len(commonprefix([k,data])) > len(k)* 0.7:
            key = k
            break
            # 使用选择发，选择一个重合度交的键
        length = len(set(data.split()) & set(k.split()))
        if length > m:
            m = length
            key = k
    #选择适合信息进行回复
    conn.sendall(words.get(key, 'Sorrey.').encode())
conn.close()
s.close()

TCP cilent

import socket
import sys
#服务端主机IP地址，和端口号
HOST = '127.0.0.1'
PORT = 50007
s =socket.socket(socket.AF_INET,socket.SOCK_STREAM)

try:#异常处理，当服务器未开启或者IP错误提示
    #连接服务器
    s.connect((HOST, PORT))
except Exception as e:
    print("Server not found or not open")
    print(e)
    sys.exit()

while True:
    c = input("Input the content you want to send:")
    #发送数据
    s.sendall(c.encode())
    #从服务器接收数据
    data = s.recv(512)
    data = data.decode()
    print("Received:" ,data)
    if c.lower() == 'bey':
        break
#关闭连接
s.close()
