Tkinter - Change Button Position on expanding window size

This is one way to organize the widgets in a grid.

I removed frame2 from the code and used just one frame ("frame") as the container.In the image above and in the code below you will see that:

• I modified the import to not use * (I've read it's not a good practice).So tk. was added as needed
• label "Example" goes in row 0, column 0 and spans for 3 cells
• label "label2" goes in row 1, column 3
• I created another label (label1) in row 1, column 2, just above button3 (I got confused, since the image you linked [Expected Output] is different from the sketch you presented in the beginning of your question
• the 3 buttons go in row 2, in columns 0, 1 and 2, respectively
• I added a pady=40 for the buttons for a better appearance
• rowconfigure and columnconfigure are needed with the weight option, in order for the grid to resize
