I think you want grid_remove().

From http://www.tkdocs.com/tutorial/grid.html:

The "forget" method of grid, taking as arguments a list of one or more slave widgets, can be used to remove slaves from the grid they're currently part of. This does not destroy the widget altogether, but takes it off the screen, as if it had not been gridded in the first place. You can grid it again later, though any grid options you'd originally assigned will have been lost.

The "remove" method of grid works the same, except that the grid options will be remembered.

Ugly example follows. Play with the grid options and the entry text to see how they are preserved.

def toggle_entry():
    global hidden
    if hidden:
        e.grid()
    else:
        e.grid_remove()
    hidden = not hidden

hidden = False
root = tk.Tk()
e = tk.Entry(root)
e.grid(row=0, column=1)
tk.Button(root, text='Toggle entry', command=toggle_entry).grid(row=0, column=0)
root.mainloop()
