This code creates a small section of a graphical user interface (GUI) using the tkinter library in Python. Here's what it does in detail:

1. Creates a label (Label widget):

   • A Label widget with the text "Include numbers?" is created and positioned at coordinates (x=20, y=100) relative to the root window using the place geometry manager.
   • This label serves as a prompt for the user to decide whether to include numbers or not.

2. Defines a StringVar variable (nums_var):

   • A StringVar object named nums_var is created with an initial value of "y".
   • This variable is used to store the selected value from the associated radio buttons.

3. Creates two Radiobutton widgets:

   • The first Radiobutton has the label "Yes", is associated with the nums_var variable, and assigns the value "y" to nums_var when selected. It is positioned at (x=200, y=100).
   • The second Radiobutton has the label "No", is also associated with the nums_var variable, and assigns "n" to nums_var when selected. It is positioned at (x=260, y=100).

4. Interactive behavior:

   • Both radio buttons are linked to the nums_var variable. Selecting "Yes" sets the value of nums_var to "y", and selecting "No" sets it to "n".
   • This mechanism allows the user to make a binary choice (Yes or No) in response to the question "Include numbers?".

In summary, this code creates a question prompt with two radio button options ("Yes" or "No") to allow the user to decide if numbers should be included, storing their selection in the variable nums_var.
