用Python實現點對點的聊天，2個程序，一個是client.py，一個是server.py，通過本機地址127.0.0.1連接進行通信，利用多線程把發送消息和接收消息分開獨立進行。
client代碼：
import socketimport sysimport threadingimport time class client(): def __init__(self): self.s = socket.socket(socket.AF_INET,socket.SOCK_STREAM) self.ip = "127.0.0.1" def connect(self): try: self.s.connect((self.ip,8888)) print("connect success") print('connect time: '+time.ctime()) except ConnectionError: print('connect error') sys.exit(-1) except: print('unexpect error') sys.exit(-1) def send_sth(self): while True: sth=input('say something:/n') try: self.s.sendall(sth.encode('utf-8')) except ConnectionError: print('connect error') sys.exit(-1) except: print('unexpect error') sys.exit(-1) def receive(self): while True: try: r=self.s.recv(1024) print ('get message:'+r.decode('utf-8')) except ConnectionError: print('connect error') sys.exit(-1) except: print('unexpect error') sys.exit(-1) c1 = client()c1.connect()threading._start_new_thread(c1.receive,())c1.send_sth()server代碼：
import socketimport sysimport threadingimport time def server(): def bind(): HOST='127.0.0.1' s.bind((HOST,8888)) print("bind ok") def listen(): s.listen(10) print ('Socket now listening') def send_sth(conn): while True: try: sth=input('say something:/n') conn.sendall(sth.encode('utf-8')) except ConnectionError: print('connect error') sys.exit(-1) except: print('unexpect error') sys.exit(-1) def recv(conn): while True: try: data=conn.recv(1024) data2=data.decode('utf-8') print('get message:'+data2) except ConnectionError: print('connect error') sys.exit(-1) except: print('unexpect error') sys.exit(-1) s=socket.socket(socket.AF_INET,socket.SOCK_STREAM) bind() listen() conn,addr=s.accept() print("connect success") print('connect time: '+time.ctime()) threading._start_new_thread(recv,(conn,)) send_sth(conn) if __name__=='__main__': server()開啟多線程有2種方法，上面2個程序都是用函數的方法，還有一種方法是用類繼承threading類
代碼：
import socketimport threadingclass client(threading.Thread): def __init__(self,sth): threading.Thread.__init__(self) self.sth=sth def run(self): s=socket.socket(socket.AF_INET,socket.SOCK_STREAM) ip="127.0.0.1" try: s.connect((ip,8888)) except : print('con error') exit() #print("connect success") s.sendall(self.sth.encode('utf-8')) #print("send success") try: r=s.recv(1024) except: print('recv error') exit() print (r.decode('utf-8'))c1=client('hello 1')c1.start()c2=client('hello 2')c2.start()以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持VEVB武林網。
