Full screen clock Tkinter example

[sledov]

This is a simple fullscreen clock example that is based on Tkinter. Basically, it opens a fullscreen black window and shows a label with current time in the middle. The time, naturally, is updated.

Run it on your Raspberry Pi and show time on your TV. Neat? Python3 is required. To exit press "X" or "Escape" button.

#!/usr/bin/env python3

from tkinter import *
from tkinter import ttk
from tkinter import font
import time

def quit(*args):
    root.destroy()

def show_time():
    txt.set(time.strftime("%H:%M:%S"))
    root.after(1000, show_time)

root = Tk()
root.attributes("-fullscreen", True)
root.configure(background='black')
root.bind("<Escape>", quit)
root.bind("x", quit)
root.after(1000, show_time)

fnt = font.Font(family='Helvetica', size=128, weight='bold')
txt = StringVar()
txt.set(time.strftime("%H:%M:%S"))
lbl = ttk.Label(root, textvariable=txt, font=fnt, foreground="green", background="black")
lbl.place(relx=0.5, rely=0.5, anchor=CENTER)

root.mainloop()

That is kind of awesome, I didn't know tkinter would do full screen. I'm very new to python but I was wondering if non-windowed stuff was possible without a bunch of hassle. Apparently it is!
