7x4 grid displaying 1 button 28 times instead of 28 different buttons being displayed. Why?

Question

I would like to display the 28 buttons below in a 7x4 self-resizing grid. As it stands now, the equal button is being displayed 28 times. I need all 28 different buttons to display in the 7x4 grid. I have all 28 different buttons configured with the row_index and col_index variables, but it's still not working. If you could help steer me in the right direction, I'd greatly appreciate it.

You are placing all of your controls at row=row_index, column=col_index. By the time that runs, row_index is 7 and col_index is 4. You need to hard-code the locations for all of those buttons, as in row_index=0, col_index=3. Then it will work. I'm looking at it now:
