Question

我写的这个程序出现的bug很奇怪修改了几次还是没有好转。问题出现在登录界面上如果第一次输入错误的密码再次输入正确密码它还提示是错误密码，但如果第一次输入的是正确密码它就正常的进入使用界面了。

```python
#-*- coding:utf-8 -*-
import tkinter as tk
from tkinter import END
import sys
import hashlib
import time
import re

end = 0
password = '3110343740'


class sign:
   #创建窗口
   def __init__(self,window):
      self.init_window = window


   #界面布局
   def set_the_window(self):
      self.init_window.title("登录界面")
      self.init_lable = tk.Label(self.init_window,text='请输入密码：；',font=('微软雅体',10),bg='Yellow')
      self.init_butter = tk.Button(self.init_window,text='登录',width=20,height=2,font=('微软雅体',12),command=self.abel)
      self.clear = tk.Button(self.init_window,text='清除',command=self.clear_text)
      self.init_text = tk.Text(show=None,width=25,height=1)
      self.state_text = tk.Text(self.init_window)

      password = password.encode('utf-8')

         end += 1
         self.init_window.destroy()
      else:

应该是状态位没有被恢复。尝试打印src中的参数.观察不等式原因。
