Python socket chat room program, pythonsocket chat room

Today, we use the python socket module to implement a chat room program.

Although the functions are relatively simple, there are still some basic functions.

Hope you can give me some advice.

Server programs:

Import socketimport threadingsock = socket. socket (socket. AF_INET, socket. SOCK_STREAM) sock. bind ('localhost', 5550) sock. listen (5) print ('server', socket. gethostbyname ('localhost'), 'listening... ') mydict = dict () mylist = list () # Pass whatToSay to the owner def tellOthers (usually tnum, whatToSay): for c in mylist: if c. fileno ()! = Repeated tnum: try: c. send (whatToSay. encode () failed T: passdef subThreadIn (myconnection, connNumber): nickname = myconnection. recv (1, 1024 ). decode () mydict [myconnection. fileno ()] = nickname mylist. append (myconnection) print ('connection', connNumber, 'has nickname: ', nickname) tellOthers (connNumber,' [system prompt: '+ mydict [connNumber] +' enter the chat room] ') while True: try: recvedMsg = myconnection. recv (1, 1024 ). decode () if RecvedMsg: print (mydict [connNumber], ':', recvedMsg) tellOthers (connNumber, mydict [connNumber] + ':' + recvedMsg) Consumer T (OSError, ConnectionResetError): try: mylist. remove (myconnection) Counter T: pass print (mydict [connNumber], 'exit, ', len (mylist), 'person left') tellOthers (connNumber,' [system prompt: '+ mydict [connNumber] +' exit chat room] ') myconnection. close () returnwhile True: connection, addr = sock. accept () pri Nt ('Accept a new connection', connection. getsockname (), connection. fileno () try: # connection. settimeout (5) buf = connection. recv (1, 1024 ). decode () if buf = '1': connection. send (B 'welcome to server! ') # Create a new thread for the current connection mythread = threading. thread (target = subThreadIn, args = (connection, connection. fileno () mythread. setDaemon (True) mythread. start () else: connection. send (B 'please go out! ') Connection. close () failed T: pass

Client Program:

import socketimport timeimport threadingsock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)sock.connect(('localhost', 5550))sock.send(b'1')print(sock.recv(1024).decode())nickName = input('input your nickname: ')sock.send(nickName.encode())def sendThreadFunc():    while True:        try:            myword = input()            sock.send(myword.encode())            #print(sock.recv(1024).decode())        except ConnectionAbortedError:            print('Server closed this connection!')        except ConnectionResetError:            print('Server is closed!')    def recvThreadFunc():    while True:        try:            otherword = sock.recv(1024)            if otherword:                print(otherword.decode())            else:                pass        except ConnectionAbortedError:            print('Server closed this connection!')        except ConnectionResetError:            print('Server is closed!')th1 = threading.Thread(target=sendThreadFunc)th2 = threading.Thread(target=recvThreadFunc)threads = [th1, th2]for t in threads :    t.setDaemon(True)    t.start()t.join()
