How do I create an attack mechanism in my turn based game in Pygame?

so im making a turn based game where the player has 3 attacks to chose from, the way I tried to do it was creating a boolean for each attack and setting it to false and when its set to true the opponents health bar would have a white rect drawn onto it to create the effect of damage and an animation would play but I can't figure out how do I make it so that this "attack" boolean is reusable, meaning every time the player uses it the rect would get longer by a certain amount. right now the attack can be used only once and it draws a single rect also the animation keeps playing on repeat since the boolean is set to true and if I set it to false then the rect would disappear, I also tried to set a variable for rect width that increases every time the attack is used but that for some reason gives the rectangle a border. How would I go about adding this attacking system? ive attached the necessary part of the code below and the entire code with prerequisite files is here

Hit = [pygame.image.load('Hit1.png'), pygame.image.load('Hit2.png'), pygame.image.load('Hit3.png')]
hitcount = 0

    global FlareonX
    global FlareonY
    global hitcount

    A2 = font.render('Quick Attack', True, black)
    A3 = font.render('Growl', True, black)

         while running:
         scr.fill(black)

                scr.fill(black)
                scr.blit(attack_scr, (70, Ay))
                f += 1
                if f >= 9:
                    break
        scr.blit(attack_scr, (Ax, Ay))
