Tkinter output

[Horia.Muntean]

this is the code of a "dice roller" I made
the output(result of print commands) shows in the terminal/cmd
is there a way to make a textbox that will show the results directly in tk?
eg. "You rolled 10 on the 1d12 dice!" #shown in a tk messagebox

and something else also.for example the dSixRoll() after it has taken a random value,can I use it for other operations?eg. theUsefulNumber = dSixRoll
it says dSixRoll is not defined(it's in a def block but I don't know how to extract it and use it for further operations)
