I'll just point out that FWIW, this is by far my favorite idiom of the 
ones offered because it applies to pretty much all the builtin container 
types:

py> d = {1:42, -37:0}
py> d2 = dict(d)
py> d == d2, d is d2
(True, False)
py> s = set(['a', 'd', 'e'])
py> s2 = set(s)
py> s == s2, s is s2
(True, False)
py> L = [3.14, 0.707]
py> L2 = list(L)
py> L == L2, L is L2
(True, False)
