[Tkinter-discuss] Filling a series of tk.Label

[Iain Day]

Sorry, here is the code that makes the label widgets:

systemdata = [[0]*len(headers)]*len(machines)

for i in range(len(machines)):
     for j in range(len(headers)):
         systemdata[i][j] = tk.Label(root, text=' ')
         systemdata[i][j].grid(row=i+1, column=j+1)


If I do the following:

systemdata[1][2].config(text='Test')

It puts "Test" into position [2][2] rather than [1][2]. It appears to 
only "see" the last row ([2]).
