How to remove an image with PyGame? [duplicate]

I want to remove an image but i don't know really how to do it. I think we have to create a function ?

import pygame
pygame.init()
pygame.display.set_caption("Képomon")
screen = pygame.display.set_mode((284*2,472*2))
BattleStartImage = pygame.image.load('assets/BattleStart.png')
buttonRondAImage = pygame.image.load('assets/buttonRondA.png')

class Button():
    def __init__(self, x, y, image, scale):
        width = image.get_width()
        height = image.get_height()
        self.image = pygame.transform.scale(image, (int(width * scale), int(height * scale)))
        self.rect = self.image.get_rect()
        self.rect.topleft = (x,y)
        self.clicked = False

    def draw(self):
        action = False
        #get mouse position
        pos = pygame.mouse.get_pos()

        #check mouseover and clicked conditions
        if self.rect.collidepoint(pos):
            if pygame.mouse.get_pressed()[0]==1 and self.clicked == False:
                self.clicked = True
                action = True

        if pygame.mouse.get_pressed()[0] == 0:
            self.clicked = False

        #draw button on screen
        screen.blit(self.image,(self.rect.x, self.rect.y))

        return action

buttonRondA = Button(427,572,buttonRondAImage,1)


running = True
while running:
    screen.blit(BattleStartImage,(161,168))

    # if buttonRondA.draw() == True:
    #   if screen.blit(BattleStartImage) == True :
    #      screen.delete(BattleStartImage)
    # doesn't work
 

    pygame.display.flip()

    for event in pygame.event.get():
        if event.type==pygame.QUIT:
            running=False
            pygame.quit()
            print("Fermeture du jeu")

I don't know what is the solution, but screen.delete , buttonRondA.draw() == True and screen.blit(BattleStartImage) doesn't work
