title: Remove the outline of an oval in Tkinter?
body: <p>By default, the circle I draw on a canvas has a black outline. I'm trying not to use a color, but somehow make the outline disappear.</p>
  
  <pre><code>import tkinter
  
  class Draw:
      def __init__(self):
          self._root_window = tkinter.Tk()
          self._canvas = tkinter.Canvas(master = self._root_window,
                                    width = 500, height = 500,
                                    background = '#1E824C')
          self._canvas.pack()
          self._canvas.create_oval(100,100,250,250, fill = 'white')
          self._root_window.mainloop
  
  if __name__ == '__main__':
      Draw()
  </code></pre>
