[Tkinter] apply command on every list element

[deanhystad]

I would use an IntVar instead of trying to talk directly to the Entry objects.

squares = []
for r in range(9):
    y = 80 + r * 40
    for c in range(9):
        var = IntVar()
        squares.append(var)
        x = 70 + c * 40
            t= tk.Entry(fenster, font=("Times New Roman",12), textvars=var)
            t.place(x=x, y=y, width=40, height=40)

Then you could use square[index].set(value) or square[index].get()
