How can I shoot a sprite from a sprite in pygame

Question

I'm trying to make simple game using pygame, where there are two ships and they shoot each other. I'm now trying to make them shoot, but since the ships are inside a group, I cannot access their rect. How can I make these ships shoot? Both the ship and the bullets are sprites.

Here is the class for the red bullets:

class RedBullet(Sprite):
    """Represent one bullet shot from the shooter."""
    
    def __init__(self, ss_game):
        """Create a bullet shot from shooter."""
        super().__init__()
        self.screen = ss_game.screen
        self.screen_rect = ss_game.screen.get_rect()
        self.color = (255, 0, 0)
        
        
        # Here is where the problem appears
        # Create bullet and place at (0, 0) and then set correct position
        self.rect = pygame.Rect(0, 0, 15, 3)       
        self.rect.right = ss_game.red_shooters.right
        
        # Set position as decimal
        self.x = float(self.rect.x)
        
    def update(self):
        """Move the bullet across the screen."""
        self.x += 1
        
        # Set rect position
        self.rect.x = self.x
        
    def draw_bullet(self):
        """Draw the bullet on the screen."""
        pygame.draw.rect(self.screen, self.color, self.rect)

The only problem I have is linking the bullet with the ship. ss_game is what I'm calling the game, and red_shooters is the group in ss_game, even though, there is only one shooter.

The Ship must "fire" the Bullet. See the following pseudo code:

class Ship(Sprite):

    def fire_bullet(self):
        new_bullet = RedBullet()
        # [...]
