I just learned python and was experimenting with tkinter for a calculator program and my formula bar does not show up. I have tried innumerous things including asking ChatGPT, but still no success.

This is all the code I am working with. I want the formula bar to be on the top and all the buttons below
>Solution :
Your formula_bar is on row=0, column=0, columnspan 6; however, you’re placing several other items on row 0 in columns 1-6 so you’re replacing the formula_bar with those widgets.
