title: draw a circles target using python
body: <p><a href="https://i.stack.imgur.com/DHmat.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/DHmat.jpg" alt="Circles"></a></p>
  
  <p>This my program using <code>turtle</code> to draw the circle target:</p>
  
  <pre><code>import turtle
  
  def origin_circle(turtle, radius):
      turtle.penup()
      turtle.goto(0, -radius)
      turtle.pendown()
      turtle.circle(radius)
  
  for radius in range(100, 200, 10):
      origin_circle(turtle, radius)
  </code></pre>
  
  <p>The code makes a moving curve, but I want the circle to be drawn at once.</p>
