title: Adding padding to a tkinter widget only on one side
body: <p>How can I add padding to a tkinter window, without tkinter centering the widget?
  I tried:</p>
  
  <pre><code> self.canvas_l = Label(self.master, text="choose a color:", font="helvetica 12")
   self.canvas_l.grid(row=9, column=1, sticky=S, ipady=30)
  </code></pre>
  
  <p>and</p>
  
  <pre><code> self.canvas_l = Label(self.master, text="choose a color:", font="helvetica 12")
   self.canvas_l.grid(row=9, column=1, rowspan=2, sticky=S, pady=30)
  </code></pre>
  
  <p>I want 30px padding only on the top of the label.</p>
