Loading... python：以前极度不屑，如今极度舒适 server.py是我的第一个python程序，client.py是第二个... 是的，这种语言就是这么简单。如果你有编程基础，你完全可以跳过Hello world，直接学习网络编程，多线程和图形界面。因为它的流行，你不必买一本关于它的入门教程书，在网上有许多参考资料。它是极其友好的。（来自C++的我感动到落泪） --- 这是一个简单的网络多人会话软件，包括服务器端server.py和客户端client.py。计划未来会加入文件传输和图形界面等。 ```py # server.py # Coco07 # 2020.9.17 import socket import threading import time MAX_GUEST_N = 2 PASSWORLD_ACC = 'zxcvbnm' SYS_BYTES = 16 MESSAGE_BYTES = 5120 guest_conns = [] guest_names = [] def broadcast(msg): for i in guest_conns: try: i.send(msg.encode()) except: pass def msg_proc(msg, conn, name): try: if msg[0:1] == 'M' or msg[0:1] == 'T': msg = name+':'+msg[1:] broadcast('M'+msg) elif msg[0:1] == 'I': msg = 'M[会话信息]会话人数:'+str(len(guest_conns)) for i in guest_names: if i == name: msg += '\n[会话信息]I' else: msg += '\n[会话信息]Guest' msg += ' '+i conn.send(msg.encode()) msg = 'M[服务器信息]服务器地址:'+str((host_name, host_port)) conn.send(msg.encode()) else: pass except: pass def guest(conn, addr, name): while True: try: name = conn.recv(64).decode() if not name in guest_names: conn.send('nameok'.encode()) guest_names.append(name) break else: conn.send('nameerr'.encode()) print(addr, '昵称设置失败') except: pass guest_conns.append(conn) print(addr, name+'进入会话') broadcast('M[服务器消息]'+name+'进入会话') while True: try: msg = conn.recv(MESSAGE_BYTES).decode() if not msg: continue msg_proc(msg, conn, name) print(addr, msg) except: guest_conns.remove(conn) guest_names.remove(name) print(addr, name+'退出会话') broadcast('M[服务器消息]'+name+'退出会话') break # main # print('Server Coco07\n') print('端口:', end='') host_name = socket.gethostname() host_port = int(input()) sk = socket.socket(socket.AF_INET, socket.SOCK_STREAM) sk.bind((host_name, host_port)) sk.listen(5) print('此服务器:', (host_name, host_port)) print('等待连接...') while True: try: conn, addr = sk.accept() print(addr, '尝试连接') passworld = conn.recv(SYS_BYTES).decode() if passworld == PASSWORLD_ACC: conn.send('y'.encode()) t = threading.Thread(target=guest, args=(conn, addr, '')) t.start() else: print(addr, '密匙错误') conn.send('n'.encode()) except: pass time.sleep(2) sk.close() ``` ```py # client.py # Coco07 # 2020.9.17 import socket import threading PASSWORLD_ACC = 'zxcvbnm' SYS_BYTES = 16 MESSAGE_BYTES = 5120 def send_msg(): while True: try: msg = input() if not msg: continue elif msg == 'text': msg = 'T' while True: temp = input() if temp == 'end': break msg = msg+'\n'+temp sk.send(msg.encode()) elif msg == 'info': sk.send('I'.encode()) elif msg == 'exit': sk.close() break else: msg = 'M'+msg sk.send(msg.encode()) except ConnectionResetError: print('[本地消息]找不到服务器') break except ConnectionAbortedError: break def recv_msg(): while True: try: msg = sk.recv(MESSAGE_BYTES).decode() if not msg: continue elif msg[0:1] == 'M': print(msg[1:]) except ConnectionResetError: print('[本地消息]找不到服务器') break except ConnectionAbortedError: break print('Client Coco07\n') print('服务器地址:', end='') serverIP = input() print('端口:', end='') serverPort = int(input()) print('正在连接服务器...') sk = socket.socket(socket.AF_INET, socket.SOCK_STREAM) sk.connect((serverIP, serverPort)) print('[本地消息]已找到服务器') sk.send(PASSWORLD_ACC.encode()) link_mood = sk.recv(SYS_BYTES).decode() if link_mood == 'y': print('[本地消息]服务器已连接') while True: print('输入昵称:', end='') myname = input() sk.send(myname.encode()) if sk.recv(SYS_BYTES).decode() == 'nameok': break else: print('[本地消息]昵称设置失败') print('[本地消息]昵称设置成功') t_send = threading.Thread(target=send_msg) t_recv = threading.Thread(target=recv_msg) ts = [t_send, t_recv] for t in ts: t.setDaemon(True) t.start() t.join() else: print('[本地消息]密匙错误') exit() sk.close() ``` ## Pyinstaller 我使用[Pyinstaller](https://www.pyinstaller.org/)将它转换为exe可执行文件。 在cmd中输入以下命令以在[清华大学开源软件镜像站](https://mirrors.tuna.tsinghua.edu.cn/)下载，比官方下载快很多。（而且我官方下载安装有问题） ``` pip install -i https://pypi.tuna.tsinghua.edu.cn/simple pyinstaller ``` 下载完成后cmd转到XXX.py的目录使用以下命令 ``` pyinstaller -F -i ICON.ico XXX.py ``` `--noconsole`即去掉cmd命令窗口。 © 允许规范转载 赞赏 如果我的文章对你有用，请随意赞赏 赞赏作者 微信

入门，要不要再来个tensorflow？
