[Tkinter] Changing the text of labels in a grid

[Carles Sadurní Anguita]

Hello,

Thanks to comp.lang.python's people I've created a grid of labels and I know
where the user clicked. I want to change the text of the clicked label.

I read that this can be done (for a single label) with

v = StrinVar()
lbl = Label(master, textvariable=v).grid()
v.set("hi, folks!")

But, how can I change the text of the label that is in (row, column)? Is it
possible to do textvariable = v[r][c] (where v is a list of lists)? Python
complains if I type 

v[r][c].set("hi!")

because v is not a StringVar. Can I create a list of lists of StringVars? Is
there any simpler way?

Thanks again.
