    enemy1_x += enemy1_speed

    # # crash event
    charactor_rect = charactor.get_rect()
    charactor_rect.left = charactor_x
    charactor_rect.top = charactor_y

    enemy1_rect = enemy1.get_rect()
    enemy1_rect.left = enemy1_x
    enemy1_rect.top = enemy1_y

    #Confirm collision
    if charactor_rect.colliderect(enemy1_rect):
        del enemy1





    screen.blit(background,(0,0)) #Drawing a background

    screen.blit(character, (character_x, character_y)) # Draw a character

    screen.blit(enemy1, (enemy1_x, enemy1_y))

    pygame.display.update() # Redraw game screen

It works well, but when my character and my enemy collide, the enemy must disappear, but when they collide, the game turns off and says NameError: name 'enemy1' is not defined. Let me know what's wrong!

 #conflict check
    if charactor_rect.colliderect(enemy1_rect):
        del enemy1

enemy1 becomes del while riding the if condition of this phrase. First of all, this is the problem.
