You sure you transcribed that correctly?
Python 2.6.6 (r266:84292, Dec 26 2010, 22:31:48)
[GCC 4.4.5] on linux2
Type "help", "copyright", "credits" or "license" for more
information.
>>> all([i>0 for i in xrange(10)])
False
>>> all(iter([i>0 for i in xrange(10)]))
False
>>> all(i>0 for i in xrange(10))
False
So unless it's something in a newer version of Python, I suspect
your examples aren't what you typed.
