Here is the error that happens if I force quit the app:
Traceback (most recent call last):
File "/Users/harrisonj11/NetBeansProjects/game_test_jakob/src/game_test_jakob.py", line 187, in <module>

for event in pygame.event.get():
pygame.error: video system not initialized
pygame.quit doesn't quit the whole program, it just uninitializes the pygame modules. So the while loop in show_go_screen is still running and calls pygame.event.get(), but that doesn't work anymore after you've uninitialized everything and the pygame.error: video system not initialized is raised.
To quit the game call sys.exit() after pygame.quit(). Add import sys at the top of the file.
Also, to run the game I had to modify the event loop in show_go_screen and remove the first while running: loop:
def show_go_screen():
screen.blit(background, background_rect)
draw_text(screen, "SHMUP!", 64, WIDTH / 2, HEIGHT / 4)
draw_text(screen, "Arrow keys move, Space to fire", 22,
WIDTH / 2, HEIGHT / 2)
draw_text(screen, "Press a key to begin", 18, WIDTH / 2, HEIGHT * 3 / 4)
pygame.display.flip()

while waiting:

sys.exit()

if event.type == pygame.KEYDOWN:
# Then you need to check if the `event.key` not `event.type`

The instruction self.rect.x(-5, 0) doesn't make any sense. You can move a sorite respectively rectangle with the pygame.Rect.move_ip instruction:
self.rect.x(-5, 0)
self.rect.move_ip(-5, 0)
Change the clouds position to the right as it goes out of the Window:
class Clouds(pygame.sprite.Sprite):
# [...]
def update(self):
self.rect.move_ip(-5, 0)
if self.rect.right <= 0:

I've been redoing a lot of my game in order to make it more efficient, before I had functions for each level and it had about 300+ repeated lines of code for each level, I've taken it out however I'm trying to get level one to function properly now.

My game is almost complete! Unfortunately, there are some little details I need to fix. The main one is that after you play for a bit, some of the sprites will get stuck on the front of the screen. Can anybody please help me out.

Press the arrow keys to move. The text box (not in the new window) will tell you your score.
You update all the enemies which are on the Group enemies
enemies.update()
And you draw all the Sprites in the group all_sprites.
for entity in all_sprites:
screen.blit(entity.surf, entity.rect)
But not all enemies which are in the Group all_sprites are in the Group enemies, too:
new_enemy = Enemy()

all_sprites.add(new_bomb)
all_sprites.add(new_blimp)
All the enemies which are in the Group all_sprites, but not in the Group enemies are drawn but don't move.
Create a random enemy type and add it to both Gourps:

elif event.type == ADDENEMY:

NameError: name 'text_objects' is not defined
You haven't defined a text_objects function. It looks like you meant the draw_text function that you declared above, but it doesn't quite do what you want either.
I'm guessing that what you meant to do was something like:
Create a text surface and a rectangle that represents the bounds of that surface
Move the rectangle to the middle of the screen (the width / 2 code)
Draw the text surface using that rectangle
You can modify the draw_text function you already have to return that stuff, since it seems to already calculate a bounding rectangle for the text and make a surface for that text as well.
So this is my game I've bean working on and so have things are going very well, the player can move around and shoot down the boxes which are ment to be moving but theres these small glitches, but before I go on heres the code:

So glitch number one:
only one of the boxers moves, I cant figure out why it only one of them is moving towards the player, all the boxers are meant to move towards the player as this is hoping to become a zombie shooter.
Glitch two:
At a random point the box that does move does stops moving in all directions but one, so lets say this happens when the box in in the center of the screen, if the player goes to the left of the box, nothing, but when the player moves to thr right of the player it moves right, but only right not up or down, and this seams to happen at soem point everytime.
Well thats it, hope you can help thanks heaps stackoverflow

Game().run()
Changes:
player can move but can leave screen
press space to pause game - but you can still move cursor and fire :)
bullet has max range - than it is removed
i change bullet vetor calculations because value was rounded to integer every frame and bullet trajectory was incorrect
bullet never change trajectory when player is moving
all code is in classes except some constant values. I add class Crosshair and Background
you can see how class (Player) handle events in event_handle
I use pygame.Rect() (screen.get_rect(), image.get_rect()) to get rect.top, rect.left, rect.center, rect.centerx, rect.topleft, etc.
There is still many things to do.
ps. if someone needs images 'ball1.png', 'ball2.png', 'ball3.png' to run this example you can find it in answer to
