title: Scrollbar appearing in the wrong spot using tkinter and Python
body: <p>I'm doing a tutorial on tkinter in Python, and the current step is to write this code:</p>
  
  <pre><code>from tkinter import *
  win=Tk()
  
  lb = Listbox(win,height=3)
  lb.pack()
  lb.insert(END,"first entry")
  lb.insert(END,"second entry")
  lb.insert(END,"third entry")
  lb.insert(END,"fourth entry")
  
  sb=Scrollbar(win,orient=VERTICAL)
  sb.pack(side=LEFT,fill=Y)
  </code></pre>
  
  <p>Apparently this is supposed to pack the scrollbar next to the list box, but instead it places it UNDER the listbox. I've tried this in both Python 2.7 and Python 3.5 with the same results. What am I doing wrong?</p>
