Having just read "Learning Python", I offer:

>>> import operator
>>> s = '''Python 1.5.2 (#1, Feb  1 2000, 16:32:16)  [GCC egcs-2.91.66 19990314/Linux (egcs- on linux-i386
... Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam'''
>>> l = list(s)           
>>> s2 = reduce(operator.add, l)
>>> s == s2
1
>>> s is s2
0
