Issues with surface.fill () in pygame

My program allows the an image to follow my mouse cursor but I am unable to draw the circle with the the Attack method because i have to suface.fill in the move method ( the move method is followMeLittleBoy) I can get the circle to draw for a split second but only while moving and it just barley. This is my full code other than my imports and such

class Hero ():

    def __init__(self):
        self.dead = False
        pygame.mouse.set_visible(False)
        self.X_MOVE_AMT = 5
        self.Y_MOVE_AMT = 5
        self.space = pygame.image.load ("hero_sprite.jpg")
        self.spaceRect = self.space.get_rect()
        self.spaceRect.topleft = (100,100)
        surface.blit (self.space, self.spaceRect)
        pygame.display.update()

    def followMeLittleBoy (self):
        amntTuple = pygame.mouse.get_pos()
        self.X_MOVE_AMT = math.ceil((amntTuple[0] - self.spaceRect.left)*0.2)
        self.Y_MOVE_AMT = math.ceil((amntTuple[1] - self.spaceRect.top)*0.2)
        self.spaceRect.left += self.X_MOVE_AMT
        self.spaceRect.top += self.Y_MOVE_AMT
        surface.blit (self.space, self.spaceRect)
        pygame.display.update()


    def Attack (self):
        surface.fill ((255,255,255))
        amntTuple = pygame.mouse.get_pos()
        pygame.draw.circle(surface, pygame.Color(0,0,255), amntTuple, 20, 2)
        surface.blit (self.space, self.spaceRect)





var = Hero ()

while True:
    surface.fill((255,255,255))
    for event in pygame.event.get():
        var.followMeLittleBoy ()
        if event.type == QUIT:
            pygame.quit()
            sys.exit()
        if event.type == KEYDOWN:
            if event.key == K_SPACE:
                var.Attack()

In a previous question I recommended you to update the state during events and call the draw routines from the main loop only once per iteration, this is specially important for the surface.fill call.

Now I strongly recommend to follow that aproach, otherwise this kind of problems will continue to arise.

There are few things that you need to fix.

  1. var.followMeLittleBoy() should be called once per loop, not for every event.

  2. You should have a seperate method for drawing in your Hero class.

  3. Call pygame.display.update() only once per loop.

I am not sure what you are trying to accomplish, but you could create a list of circles that are to be drawn, and when you press spacebar, a circle is added to a list.

Then you can loop your circle list,and draw each of them without them dissapearing.
