Tkinter, a lot of buttons, make prog shorter?

[skanemupp at yahoo.se]

is there anyway to make this shorter? i hate having these big blocks
of similar-looking code, very unaesthetic.
maybe doesnt matter good-code-wise?
anyway can i make some function that makes this shorter?
like put the etiquettes on the button froma string of
'123+456-789*0Cr/' ?
problem is the command and lambda-func for each button is different.
