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()
