The above would produce
[{1: 4}, {1: 5}, {1: 6}, {2: 4}, {2: 5}, {2: 6}, {3: 4}, {3: 5}, {3: 6}]
If, on the other hand, you tried to make a single dictionary with
{x: y for x in (1, 2, 3) for y in (4, 5, 6)}
it doesn't make a lot of sense (multiple y's for the same x?). The
only thing i could imagine it producing, perhaps, is
{1: 6, 2: 6, 3: 6}
