Yay! Python2.5 fixed my approach to this, I tried
from collections import defaultdict
f=file('c:\\test.txt')
lines=f.readlines()
f.close()
d=defaultdict(list)
[ d[l.split()[0]].append(l.split()[1]) for l in lines ]

For k,v in d.items():
print k,v
I get
AttributeError: 'list' object has no attribute 'items'
