I am trying to create this GUI in Tkinter. I have created a 2×2 grid of buttons using a grid. I want Radio Buttons to span equal to the width of 2×2 buttons or buttons to span the width of radio buttons. Since we can’t specify 1.5 (floats) as columns how to do this?

>Solution :

There are a few possibilities. Arguably the simplest would be to create a 6×3 grid. The buttons at the top each occupy 3 columns, the buttons along the bottom each take up two columns.
