On copying arrays

[ernesto.adorio]

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.

Regards,
Ernie.

ernesto:

best = list(test)

may be faster than:

best = [x for x in test]
