How to get the value of a checkbox

Question

I have a checkbutton in my program but when I click the checkbox, it gives me the following error: TypeError: get() missing 1 required positional argument: 'self' Below is the code along with the related function. When I check the check box, it is supposed to take off the tax in the taxe field.

You need to instantiate IntVar first. I.e. (Note the () after the IntVar)

var13 = IntVar()

A very similar problem with a solution can be found here: https://stackoverflow.com/a/17534363 – chumbaloo May 14 '20 at 14:02
Sorry, but that didn't help my particular problem. – codemonster May 14 '20 at 14:07

Could you provide the complete code? As a bare minimum the definition of IntVar Unless .get() is a static method, you need to instantiate the IntVar. – chumbaloo May 14 '20 at 14:09
When I click the check button, I print the value and it prints the following: – codemonster May 14 '20 at 14:32
You need to put () after IntVar. So don't do: var13 = IntVar, do var13 = IntVar() instead – chumbaloo May 14 '20 at 14:33
I did that and instead of printing 1 or 0 it prints: PY_VAR1 – codemonster May 14 '20 at 14:37
Ok, I figured it out. I changed from TopLevel() to Tk() Why that makes a difference I don't know but it worked. – codemonster May 14 '20 at 14:54
