pyopengl help

hi everyone,
i'm not sure if this is the best place for this post, but since i'm a novice at pyopengl, i thought this might be the place. i have this piece of code which is giving some errors and would like some feedback as to why this is so.
using pyopengl. i have a simple list and would like with my mousebutton select the one of the items from the list when the button is pressed. any help on this would be great.

thank you in advance...

print letters

for c in text:
glutStrokeCharacter(font, ord(c))

def draw():

for a in letters:
glPushMatrix()
glTranslatef(a[3], a[3], 3)
glColor3fv(a[2])

def mousebutton(button, state, x, y):
print button, state
