python实现倒计时小工具
本文实例为大家分享了python实现倒计时小工具的具体代码，供大家参考，具体内容如下
#!/usr/bin/envpython
#coding=utf-8
importthreading
importtime
importQueue
fromTkinterimport*
importtkMessageBox
importlogging
logging.basicConfig(level=logging.INFO)
##Communicationqueue

##Functionruninthread
deftimeThread():
globalg_time
g_time=timeVar.get()*60
while1:
logging.info("线程放入队列:%d".decode("utf-8")%g_time)
commQueue.put(g_time)
try:
root.event_generate('<>',when='tail')
exceptTclError:
break
time.sleep(1)
g_time-=1
ifg_time==-1:
begin_btn["fg"]="black"
clockVar.set("开始计时")
break
deftimeChanged(event):
x=commQueue.get()
logging.info("获取队列:%d".decode("utf-8")%x)
minits=x//60
seconds=x%60
s="剩余时间{:02}:{:02}".format(minits,seconds)
begin_btn["fg"]="blue"
clockVar.set(s)
ifx==0:
tkMessageBox.showinfo("提醒","时间已到")
defclock_func(*args):
globalg_time
ifthreading.activeCount()>1:
g_time=timeVar.get()*60
else:
th=threading.Thread(target=timeThread)
th.start()
##Createmainwindow
root=Tk()
root.title("计时工具")
root.geometry("180x95-0-45")
root.resizable(width=FALSE,height=FALSE)
root.wm_attributes("-topmost",1)

frame.pack()
Label(frame,text="设定时间间隔").grid(row=1,column=2)

begin_btn.grid(row=3,column=2)

forchildinframe.winfo_children():
child.grid_configure(pady=3)
time_entry.focus()
root.bind('<>',timeChanged)
root.bind("",clock_func)
root.mainloop()
小编再为大家分享一段代码：Python窗口倒计时

defGetSource():

Tkinter.Button(get_window,text="Change",
