    if counter == 0:
        status = 1 
    label.config(text=str(counter))

    label.after(1000,counter_label)


print(counter)

root = tk.Tk()
root.title("Counting Seconds")
label = tk.Label(root, fg="green")
label.pack()
counter_label(label)

root.mainloop()

CodePudding user response：

your recursive call

label.after(1000,counter_label)

can be modified to include label argument with an anonymous function

label.after(1000,lambda x=label: counter_label(x))
