效果图：

客户端代码：

import tkinter as tkfrom tkinter import scrolledtextimport socketimport threadingfrom datetime import datetime def tcp_recv(sock):    while True:        str = sock.recv(1024).decode("utf-8")        show_info(str)def send_func(sock):    str = send_msg.get("0.0", "end")    sock.send(str.encode("utf-8"))    show_info(str) def show_info(str):    now = datetime.now()    s_time = now.strftime("%Y-%m-%d %H:%M:%S")    str = str.rstrip()    if len(str) == 0:        return -1    send_msg.delete("0.0", "end")    temp = s_time + "\n    " + str + "\n"    show_msg.insert(tk.INSERT, "%s" % temp) msFont = '微软雅黑' #字体fontSize = 18 #字体大小sock = socket.socket(socket.AF_INET,socket.SOCK_STREAM)sock.connect(("127.0.0.1",8888)) mainWindow = tk.Tk()mainWindow.title("客户端")mainWindow.minsize(400,400)show_msg = scrolledtext.ScrolledText(mainWindow,font=(msFont,fontSize))show_msg.place(width=400,height=250,x=0,y=0)#show_msg.insert(tk.INSERT,"%s 已连接\n"%addr[0])send_msg = scrolledtext.ScrolledText(mainWindow,font=(msFont,fontSize))send_msg.place(width=400,height=140,x=0,y=260)button_send = tk.Button( mainWindow, font=(msFont,fontSize),text = "发  送",bg="orange",fg="white",                         command=lambda:send_func(sock))button_send.place(width=100,height=40,x=300,y=360) t = threading.Thread(target=tcp_recv,args=(sock,))t.start()tk.mainloop()

服务器代码：

import tkinter as tkfrom tkinter import scrolledtextimport socketimport threadingfrom datetime import datetime def tcp_recv(sock):    while True:        str = sock.recv(1024).decode("utf-8")        show_info(str)def send_func(sock):    str = send_msg.get("0.0", "end")    sock.send(str.encode("utf-8"))    show_info(str) def show_info(str):    now = datetime.now()    s_time = now.strftime("%Y-%m-%d %H:%M:%S")    str = str.rstrip()    if len(str) == 0:        return -1    send_msg.delete("0.0", "end")    temp = s_time + "\n    " + str + "\n"    show_msg.insert(tk.INSERT, "%s" % temp) msFont = '微软雅黑' #字体fontSize = 18 #字体大小sock = socket.socket(socket.AF_INET,socket.SOCK_STREAM)sock.bind(("127.0.0.1",8888))sock.listen(5) mainWindow = tk.Tk()mainWindow.title("服务器")mainWindow.minsize(400,400)show_msg = scrolledtext.ScrolledText(mainWindow,font=(msFont,fontSize))show_msg.place(width=400,height=250,x=0,y=0)send_msg = scrolledtext.ScrolledText(mainWindow,font=(msFont,fontSize))send_msg.place(width=400,height=140,x=0,y=260)button_send = tk.Button( mainWindow, font=(msFont,fontSize),text = "发  送",bg="orange",fg="white",                         command=lambda:send_func(s))button_send.place(width=100,height=40,x=300,y=360) s,addr = sock.accept()t = threading.Thread(target=tcp_recv,args=(s,))t.start()tk.mainloop()
