title: Random fill colour for shapes in Python(TKinter)
body: <p>I am wondering how to get a random color out of a list to use in the <code>draw_rectangle()</code></p>
  
  <pre><code>colors = ["red", "orange", "yellow", "green", "blue", "violet"]
  
  canvas.create_rectangle(self.x, self.y, self.x + 60, self.y + 60, fill = random.choice(colors))
  </code></pre>
  
  <p>This causes my code to crash, what else can I try?</p>
