Python Tkinter 简单登录界面的实现

如下所示：fromtkinterimport*classReg(Frame):def__init__(self,master):frame=Frame(master)frame.pack()self.lab1=Label

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()
