title: Tkinter button resize
body: <p>From <a href="https://stackoverflow.com/a/14247813/7416363">this</a> I found how to resize a button, so I tried to execute this code.</p>
  
  <pre><code>from tkinter import * 
  selection_window = Tk()
  selection_window.wm_title("")
  selection_window.geometry('{}x{}'.format(200, 150))
  frame_1 = Frame(selection_window, width=200, height=30)
  Button(frame_1, text="Single",height = 100).pack(side=LEFT,anchor=S)
  Button(frame_1,text="Range",command=Toplevel,height = 20).pack(side=RIGHT,anchor=S)
  frame_1.pack()
  selection_window.mainloop()
  </code></pre>
  
  <p>But the size of button is not changed, rather, the buttons went to the center of the window. Can someone please tell me why is the problem? </p>
