How to not lose all of the hearts when you touch the box

Here is my whole code. I want it to whenever you touch the box you will use one heart only. But if i touch it now I loose all of the hearts imidiatelly. Pls help. I thinks it works correctly but whever I touch the box I lose 1 heart then another again and another without having time to get out of the box. Please help.

I tried to fix it but I was not able. I know what the problem is but im not able to fix it.

>Solution :

Add a state that indicates whether the player collided with the box in the previous frame and don’t decrease the number of hearts more than once if the player collides with the box in consecutive frames:

collided_in_the_last_frame = False
while True:
    # [...]

    if active:

        collides = player_rect.colliderect(box_rect)
        if collides and not collided_in_the_last_frame: 
            hearts -= 1
        collided_in_the_last_frame = collides

        # [...]
