there's no t_one variable in your program.  assigning some stuff to
a variable doesn't create a variable with that name (if your python
tutorial told you that you could do that, make sure you get your
money back).

the usual way to store a list of values (widgets) is to use a list:

    var = []
    for x in range(3):
        textbox = entry(frame)
        textbox.grid(row=4+i, column=0)
        var.append(textbox)

    print var[0].get() # returns the content of the first textbox
    print var[1].get() # same, for the second textbox
    print var[2].get() # same, for the third textbox
