tk.Label(master, text="First Name").grid(row=0)
tk.Label(master, text="Last Name").grid(row=1)

e1 = tk.Entry(master)
e2 = tk.Entry(master)
e1.insert(10, "Miller")
e2.insert(10, "Jill")

    label3 = tk.Label(root, text= 'The Square Root of ' + x1 + ' is:',font=('helvetica', 10))
    canvas1.create_window(200, 210, window=label3)
