Keybind that binds to every key in tkinter
I use <Key> it will capture any keyboard event and print "Hello". And don't forget to specify event or event=None parameter in testing() .
from tkinter import *window = Tk()root = Canvas(window, width=500, height=500)def testing(event): print("Hello!")def countdown(count, label): label['text'] = count if count > -1: root.after(1000, countdown, count-1, label) elif count == 0: label['text'] = 'Time Expired' elif count < 0: label.destroy()root.bind_all('<Key>', testing)root.pack()root.mainloop()
