title: Determine which Button was pressed in Tkinter?
body: <p>I'm making a simple little utility while learning Python.  It dynamically generates a list of buttons:</p>
  
  <pre><code>for method in methods:
      button = Button(self.methodFrame, text=method, command=self.populateMethod)
      button.pack({'fill': 'x', 'expand': 1, 'padx': 5, 'pady': 3})
  </code></pre>
  
  <p>That part works fine.  However, I need to know which of the buttons was pressed inside <code>self.populateMethod</code>.  Any advice on how I might be able to tell?</p>
