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 timefrom tkinter import Tk,Labelclass 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()
