shortest possible python pascal triangle code
This is a bit shorter, but still no good:

 

l=[1]
while(len(l)&lt;32):
 print' '.join(map(str,l))
 l=[1]+map(int.__add__,l,l[1:]+[0])


And this one comes in at a score of 8.28 (credit to @primo):

l=[1];exec"print' '.join(map(str,l));l=map(sum,zip([0]+l,l+[0]));"*31
