Dict comprehension:
{i: x for i, x in enumerate([1, 2, 3])} # returns {0: 1, 1: 2, 2: 3}
if you happen to have a bunch of object with some kind of an id field (like I do) you can do this:
id
{x['id']: x for x in [{'id': 3}, {'id': 4}, {'id': 5}]} # returns {3: {'id': 3}, 4: {'id': 4}, 5: {'id': 5}}
which is sometimes pretty neat I think.
