[Tkinter] Have tkinter button toggle on and off a continuously running function

[AnotherSam]

Tkinter buttons don't toggle. How about a checkbox?

Yes, that's the main issue here. I usually pass a variable to keep track of the button state, but not so in this case. After seeing the solution regarding the button, and how much code it takes, I am very interested in how you would do this with a check box.
