I don't think it is equivalent:
Python 2.4.4 (#1, Oct 23 2006, 13:58:00)
[GCC 4.1.1 20061011 (Red Hat 4.1.1-30)] on linux2

>>> a = [1,2,3]
>>> b = [4,5,6]
>>> a[1:] = b # the idea is to simulate (setf (cdr a) b)
>>> print a
[1, 4, 5, 6]
>>> b[0] = 9 # (setf (car b) 9)
>>> print a
[1, 4, 5, 6] # would expect [1,9,5,6]
