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()
