On copying arrays

[ernesto.adorio at gmail.com]

Is there a conceptual difference between
    best =test[:]
and
   best = [x for x in test] ?
test is a list of real numbers. Had to use the second form to avoid a
nasty bug
in a program I am writing. I have to add too that I was using psyco
in Python 2.5.1.

Ernie.
