本文实例讲述了python实现的简单窗口倒计时界面。分享给大家供大家参考。具体分析如下：

下面的代码通过Tkinter制作windows窗口界面，然后时间了一个简单的倒计时功能，代码可以直接运行

# Countdown using Tkinter 
from Tkinter import *
import time
import tkMessageBox
class App:
 def __init__(self,master):
  frame = Frame(master)
  frame.pack()
  self.entryWidget = Entry(frame)
  self.entryWidget["width"] = 15
  self.entryWidget.pack(side=LEFT)
  self.hi_there = Button(frame,text="Start",command=self.start)
  self.hi_there.pack(side=LEFT)
  self.button = Button(frame,text="QUIT",fg="red",command=frame.quit)
  self.button.pack(side=LEFT)
 def start(self):
  text = self.entryWidget.get().strip()
  if text != "":
   num = int(text)
   self.countDown(num)
 def countDown(self,seconds):
  lbl1.config(bg='yellow')
  lbl1.config(height=3, font=('times',20,'bold'))
  for k in range(seconds, 0, -1):
   lbl1["text"] = k
   root.update()
   time.sleep(1)
  lbl1.config(bg='red')
  lbl1.config(fg='white')
  lbl1["text"] = "Time up!"
  tkMessageBox.showinfo("Time up!","Time up!")
 def GetSource():
  get_window = Tkinter.Toplevel(root)
  get_window.title('Source File"Change",
      command=lambda: update_specs()).pack()
root = Tk()
root.title("Countdown")
lbl1 = Label()
lbl1.pack(fill=BOTH, expand=1)
app = App(root)
root.mainloop()

希望本文所述对大家的Python程序设计有所帮助。
