"For me"? No. It is, pure and simply, a fact about Python. That is how
the language is defined. It's not "for me" a fact, as if facts might
not be facts for other people. That isn't how facts work, and it isn't
how Python works.
Here's some documentation on the iterator protocol, and if you want to
discuss further, python-list hasn't had a long and rambling thread on
"why are iterators the way they are" for a while... have fun.
