Nope, nothing to do with it. Read the ref manual on chained comparision operators. http://www.python.org/doc/2.4/ref/comparisons.html#l2h-430 For proof, run the given code in the original post. It's not faked in the slightest, and the manual holds the key to understanding. -- http://mail.python.org/mailman/listinfo/python-list

that is it is not it (logic in Python)
I want to know if iter(iterator) returns always its argument (when argument is an iterator) So : >>> iterable = range(10) >>> it = iter(iterable) >>> that = iter(it) >>> that is it True# Good! >>> that is it is not it False # What ? >>> >>> Python = map(bool, it) >>> logic = True >>> logic in Python is not it True # That was close! >>> >>> that is it or it is not it True >>> >>> # from physics.constant import N >>> N = 6.02e+27 >>> big = 192 # cm 1.92 meter is big for me (see my name) >>> N is big False # what ? >>> -- Seriously on an April fool's day. -- http://mail.python.org/mailman/listinfo/python-list
