I’m not sure that I understood you right, but try this:

import pygame
Import Random
Width = 1200.
Height = 400.
FPS = 60.
# Set colors
White = (255, 255, 255)
Black = (0, 0, 0)
RED = (255, 0, 0)
Green = (0, 255, 0)
Blue = (0, 0, 255)
Yellow = (255, 255, 0)
# Variables
Timer_Games = 0.
#Other
pygame.time.set_timer (pygame.userevent, 1000) # timer watching instructions
LLL = 60.
# Create a game and window
pygame.init ()
pygame.mixer.init ()
screen = pygame.display.set_mode ((Width, Height))
pygame.display.set_caption ("Shmup!")
Clock = pygame.time.clock ()
Class MOB3 (pygame.sprite.sprite):
  Def __init __ (Self, LLL): # +++ LLL
    Super () .__ init __ () # +++
    Pygame.Sprite.Sprite .__ INIT __ (SELF)
    self.image = pygame.surface ((60, 900))
# Self.Image.fill (Yellow)
    c = random.sample ([Yellow, Blue, Green, Red, White], 1) [0] # +
    self.image.fill (C) # +
    self.image.set_alpha (150)
    self.Rect = Self.Image.get_rect ()
    Self.Rect.centerX = LLL
    Self.Rect.centery = Height / 2
    # Self.Rect.y = Random.randrange (-100, -40)
    Self.Speedy = 4.
All_sprites = pygame.sprite.group ()
mobs1 = pygame.sprite.group ()

    If e.Type == Pygame.useRevent: # Only the timer works in his borders

          All_sprites.add (q)
          mobs1.add (q)
          LLL + = 150 # 200
    If e.type == pygame.quit:

pygame.quit ()
