With experience you begin to expect them and check your assumptions more often. There have been countless times I've written unit tests for tiny functions that I couldn't possibly have written wrong, only to discover that I have in fact made a silly mistake.

Re: [pygame] Never seen this before
Happens to everyone. It takes time(10 years or 10,000 hours) to get good at
something. I'm at about year 6-7 and I find while I still make silly
mistakes, I've become much better at catching them before or during testing.

Re: [pygame] Never seen this before
oops. I should add that to my list of dumb bugs i find in the code i write.
Like this one:
if key[K_RIGHT]:
spaceship.speed = spaceship.speed+10
if key[K_RIGHT]:
spaceship.speed = spaceship.speed-10

Okay, I had assumed you had written your own python class, subclassing one of
the Group classes, and had used .add within the overridden method. I've made
that mistake myself.
Looking at your code, I see the issue. For one, Group.add takes in a list of
sprites. You are passing in three separate arguments, and Group.add is thinking
they are each sprites.
You should change
enemies.add(random.choice(("enemyblue.png", "enemycyan.png", "enemygrey.png",
"enemyyellow.png")), item, enemybullets)
to
enemies.add(Enemy(random.choice(("enemyblue.png", "enemycyan.png",
"enemygrey.png", "enemyyellow.png")), item, enemybullets))
The super method can take a class and an object as parameters, and it will call
the method on the superclass of the class given. It is the same as
Basicsprite.__init__(self, img)
For reference, here is the documentation about Group.add:
http://www.pygame.org/docs/ref/sprite.html#Group.add

You get that kind of error when you use a recursive function, and it recurses
down further than Python has room on the stack for. Typically, when you get
this error, there's something wrong with your recursive function. What it
appears to be doing is within your add function, its calling itself again. I
think you might be wanting to call super(C, self).add(spr) where C is the class
you created which has the add method.
