My variables don’t want to show up even after i define them it gives me an error that the variable doesn’t exist

this is the problem with the code because I don’t know how to properly explain it

Here is the code in typed form as well

        def convert6(tog = [0]):

        tog[0] = not tog[0]
        if tog[0]:
            print('Server DIF Hard ON')
            difHardS = 1

        else:
            print('Server DIF Hard OFF')
            difHardS = 0

    button3 = tk.Button(self, text="Hard", command=convert6, height=2, width=20)
    button3.pack()
if difHardS = 1:

Answer

You are using difHardS variable within the method (I assume) which is nowhere defined in the method. This is the problem that the editor describes.
