如下所示：

from tkinter import * class Reg (Frame): def __init__(self,master): frame = Frame(master) frame.pack() self.lab1 = Label(frame,text = "账户:") self.lab1.grid(row = 0,column = 0,sticky = W) self.ent1 = Entry(frame) self.ent1.grid(row = 0,column = 1,sticky = W) self.lab2 = Label(frame,text = "密码:") self.lab2.grid(row = 1,column = 0) self.ent2 = Entry(frame,show = "*") self.ent2.grid(row = 1,column = 1,sticky = W) self.button = Button(frame,text = "登录",command = self.Submit) self.button.grid(row = 2,column = 1,sticky = E) self.lab3 = Label(frame,text = "") self.lab3.grid(row = 3,column = 0,sticky = W) self.button2 = Button(frame,text = "退出",command = frame.quit) self.button2.grid(row = 3,column = 3,sticky = E) def Submit(self): s1 = self.ent1.get() s2 = self.ent2.get() if s1 == 'admin' and s2 == '123': self.lab3["text"] = "登陆成功" else: self.lab3["text"] = "用户名或密码错误!" self.ent1.delete(0,len(s1)) self.ent2.delete(0,len(s2))root = Tk()root.title("用户登录")app = Reg(root)root.mainloop()
