title: Have multiple commands when button is pressed
body: <p>I want to run multiple functions when I click a button. For example I want my button to look like</p>
  
  <pre><code>self.testButton = Button(self, text = "test", 
                           command = func1(), command = func2())
  </code></pre>
  
  <p>when I execute this statement I get an error because I cannot allocate something to an argument twice. How can I make command execute multiple functions.</p>
