that is it is not it (logic in Python)

[F. Petitjean]

I want to know if iter(iterator) returns always its argument (when
argument is an iterator)

So :

I want to know if iter(iterator) returns always its argument (when
argument is an iterator)

By the strict definition of iterator (versus iterable) that requires that
as a condition to be an iterator, then yes. If you use a looser definition
of iterator, then perhaps not.

This is equivalent to '(that is it) and (it is not it)' which is clearly
false.

False # What ?

Reread the ref manual on chained comparison operators.

Nope, nothing to do with it. Read the ref manual on chained comparision
operators.

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.

*I* wrote the original post. and am pretty sure it is not faked. And I
run it before posting to be sure not to say anything wrong. it is a kind
of relief to learn that computers in 2005 (even Python powered) are
humor-impaired and follow the « ref manual » every time even on first
April.

But you also wrote in your original post:

Seriously on an April fool's day.

which would seem to be falsely denying that your post was an April
Fool's prank. Rather bad form, old chap ;-)
