The tutorials and such stress that python doesn't
typically care about a specific "True" or "False"; the
normal distinction is between "empty" and "not empty".
0, None, (), [], {} all come out as false.
"Is there anything left?" is a pretty analogy for iterators,
particularly since the examples tend to start with list
or file iterators.
x = [] or iter([]) or "nope" does just what *I* expect.
If you want to change it back, so be it, but it will break
code that way too; please at least make big notes in
the documentation.
