Python: objects in a list

Question

How do I make it so that the circles in this list can be modified or removed later on? Isn't the list different from the actual objects?

def drawAllBubbles(window,numOfBubbles):
    bublist=list()
    for x in range(numOfBubbles):
        p1= random.randrange(1000)
        p2= random.randrange(1000)
        center= graphics.Point(p1,p2)
        bubx = center.getX()
        buby = center.getY()
        r = random.randint(1, 255)#randomize rgb values
        g = random.randint(1, 255)
        b = random.randint(1, 255)
        circle = graphics.Circle(center, 5)
        circle.setFill(color_rgb(r, g, b))
        circle.setOutline("black")
        circle.draw(window)
        bublist.append(circle)
    return bublist
    window.getMouse()

This part of the script essentially draws

And then returns a list of circles.

bublist contains the circles. They can be retrieved, used, modified, removed... — wwii

@wwii Would I be able to run "getX()" and "getY()" for each circle in the list? — aero26

The objects are contained in bublist

If you iterate over the list, you can change, remove, or redraw the circles. For example:

for bubble in bublist:
    bubble.setOutline("green")
    bubble.draw(window)

for bubble in bublist: a= bubble.getCenter() ` b = a.getX()` c = a.getY() print(a) For some reason, I can't get this to print.

@aero26 That line of code will try to print a, which refers to the Point object returned by bubble.getCenter(). I assume you're trying to print the coordinates, in which case you should try print((b, c)). In Python 2.x: print (b, c)
