What would this look like if i want to use a straight up built-in
dictionary type and not the collections.defaultdict.
Not too different:
import collections
def foo():
lookup = collections.defaultdict(list)
x = range(10)
y = range(5, 15)
z = range(8, 22)
sets = {'x': set(x), 'y': set(y), 'z': set(z)}
for key, value in sets.items():
for element in value:
lookup[element] = lookup.get(element, []).append(key)
print "\n", lookup, "\n\n"
for x in lookup:
lookup[x].sort()
print x, lookup[x]
print "\n"
At least I think thats all you need here.
