title: Using Python to verify the mouse position is within the circle, when clicking anywhere within the circle.
body: <p>I am working on a project within Python that is to determine the multi-tasking efficiency of a person. Part of the project is to have a user respond to an event on screen using the mouse. I have decided to have the user click within a ball. However I am having issues with my code on verifying that the mouse cursor is actually within the confines of the circle.</p>
  
  <p>The code for the methods in question are below. Radius of the circle is 10. </p>
  
  <pre><code>    #boolean method to determine if the cursor is within the position of the circle
      @classmethod
      def is_valid_mouse_click_position(cls, the_ball, mouse_position):
          return (mouse_position) == ((range((the_ball.x - 10),(the_ball.x + 10)), 
                                   range((the_ball.y + 10), (the_ball.y - 10))))
  
      #method called when a pygame.event.MOUSEBUTTONDOWN is detected.
      def handle_mouse_click(self):
      print (Ball.is_valid_mouse_click_position(self.the_ball,pygame.mouse.get_pos))
  </code></pre>
  
  <p>No matter where I click within the circle, the boolean still returns False. </p>
