python使用tkinter实现屏幕中间倒计时

本文实例为大家分享了python实现屏幕中间倒计时的具体代码,供大家参考,具体内容如下

先看下效果图:

代码:

import time

from tkinter import Tk,Label

class TimeShow():#实现倒计时

def __init__(self,time_show=5):

self.timeShowWin=Tk()

self.timeShowWin.overrideredirect(True)

self.timeShowWin.attributes('-alpha',1)

self.timeShowWin.attributes('-topmost',True)

self.timeShowWin.attributes('-transparentcolor','black')

self.time_show = time_show

self.time_label=Label(self.timeShowWin,text='倒计时{}秒'.format(self.time_show),font=('楷体',25),fg='red',bg='black')

self.time_label.pack(fill='x',anchor='center')

self.timeShowWin.geometry('+'+str(int(self.timeShowWin.winfo_screenwidth()/2))+'+'+str(125))

self.timeShowWin.after(1,self.show)

def show(self):

while self.time_show >= 0:

print('time_label={}'.format(self.time_label))

self.time_label['text']= '倒计时{}秒'.format(self.time_show)

self.timeShowWin.update()

self.time_show -= 1

time.sleep(1)

self.timeShowWin.destroy()

def start(self):

print('ok')

self.timeShowWin.mainloop()

if __name__ == '__main__':

a=TimeShow(10)

a.start()
