# Iterator = An object that returns elements one at a time
# from a sequence (or data stream)
# and remembers its position between calls.
# A Python object is an iterator if it has:
# __iter__() → Returns the iterator object itself
# __next__() → Returns the next item in the sequence
# (raises StopIteration when there's no more items)
