Question

pygame.init()

# create the canvas object
# here we pass it a size of 800x600
canvas = pygame.display.set_mode((800, 600))

scene = pygame.Surface(canvas.get_size())
scene.fill((0, 0, 0))

f15 = Jet()
exocet  = Missile()

container = pygame.sprite.Group().   # create an instance of class Group
container.add(f15,exocet)                       # add  f15 and exocet object in the container        

running = True

while running:
    for event in pygame.event.get():
         if event.type == KEYDOWN:
             if event.key == K_ESCAPE:
                 running = False
         elif event.type == QUIT:
             running = False
        
     canvas.blit(scene, (0, 0))
 
     container.update()   
     container.draw(canvas)

     pygame.display.flip()

Answer 1

Your first mistake would be that in order to use pygame, you have to first import the pygame module. You also seem to be making calls to Jet() and Missle() without any definitions. If the definitions are in modules you have written, you need to import those also.
