These list comprehensions are all approximately equivalent::
# Calling the function twice stuff = [[f(x), f(x)] for x in range(5)]
stuff = [[y, y] for y in (f(x) for x in range(5))]
Why not `stuff = [[y, y] for y in map(f, range(5))]`? It is currently the fastest and most readable version IMHO.
With kind regards, -gdg
