Changing Value Through Button or Checkbox in Tkinter

Question

My Whole Program is Working in a Loop like this

myWindow = Tk()
myWindow.title("Live Data")
myWindow.geometry("500x600")

def my_mainloop():
    statements....
    myWindow.after(1000, my_mainloop)

myWindow.after(1000, my_mainloop)
myWindow.mainloop()

I want to implement something(button/checkbox), which is changing a value in variable like 0 and 1

so i can use this value (0/1) in this infinite loop to code my logic

A Click will change value to 1 and then another click will change value to 0.

Thank you.

@Jordan that is related running a While True loop in Tkinter, and yes the program reaches the last line, even i don't know how, but it does. — SilentHG, Apr 24 '20 at 17:48
@stovfl i don't want to toggle value through code, i want to toggle through GUI — SilentHG, Apr 24 '20 at 17:49
@stovfl that statement represents that all the coding is there, end_user wants to toggle values through GUI, not by opening code and changing the value there — SilentHG, Apr 24 '20 at 17:58
