Repeating elements in list comprehension

Question

I have this list comprehension:

[[x,x] for x in range(3)]

which results in this list:

[[0, 0], [1, 1], [2, 2]]

Answer 1

You might get away with this:

[floor(x/2) for x in range(6)]

edit1

[int(x/2) for x in range(6)]

is the more portable solution in the same vein. Although the other presented answers seem better.
