If you don't immediately see the results of your actions, how do you know that you performed the action correctly? For your example I would put a button in frame 2 that draws a dialog to enter values for first_no and second_no which are applied when you press the "Ok" button in the dialog, or ignored if you press the "Cancel" button.
I cannot tell you what is a good design for your application (I don't know what you are trying to achieve), but I can say you should be spending most of your programming time thinking about the user experience and relatively little time writing code.
You are right. I am a little new to tkinter. with this code for summation and the one I just said to open a textfile, I am trying to learn.
I want to make an app to get variables (from entry boxes, or from importing a file), and pass these variables through pages. This was an easy example I just created to learn the basics and then move to the harder cases.
Thank you
