Help with Calculater (first program)

[aToaster]

Hey guys, I'm just getting the hang of Python and Tkinter and I could
use some help. I wrote most of the gui for my calculator program,
well I haven't gotten around to putting in the
plus/minus/divide/mulitply yet but I'll save that for later. Right
now I want the buttons to display the number in the entry field. How
can I pass the values into the entry field as they are being clicked?
Oh and here's my biggest question. Right now I have it set so that if
you press 3 and 4 it gives you 7, but what I want it to do is if you
press 3 and then 4 it gives you 34. How would I be able to do that?
I appreciate the help! Thanks.

Mine too!
I think the answer to your biggest question is to mutiply 3 by ten
before 4 is added to it, that would be a simple change.
