Python tkinter break function loop

Question

def buttonWeiterClick(y):
    def skip():
        buttonWeiterClick(1)
    if y == 1:
        x = ampel.getZustand()
        print(x,y)
        anzeigeAktualisieren(x,y)
        ampel.schalten()
        ampel2.schalten()
        fenster.after(3000, skip)
    elif y == 2:
        print("Crashed")

I got a function which calls himself constantly via an .after Statement and I want to know if and how I can end this loop for example via a Button?

make the loop to check for a bool variable to be true always. And then when you press a button; make that variable false. — Vicrobot, Jan 16 '19 at 18:15

You can store the result of the after function call in some variable after_id, and then in your button callback do fenster.after_cancel(after_id)
