Forget about eval!
Use a dictionary: keys are bucket names, values a list containing all
associated items. You will find the setdefault method very useful.
d = {}
for each item, do: d.setdefault(bucket, []).append(item)
If you are using Python 2.5, use a defaultdict instead, the very first
example looks like what you want.
