To align the button text to the left of the button rectangle, Simply set the justify argument of the button to LEFT.

btna = Button(root, text = "按钮", command = go, justify = LEFT, borderwidth = 3)
btna.place(x = e, y = a, anchor = Nw, width = 28e, height = a)

The default value of this parameter is CENTER, which means that the text is aligned in the center. You can change it to LEFT to make the text aligned in the left.
