There is __iter__, but no next() or __next__() on the string itself.
__iter__ makes something iterable; __next__ is on iterators, but not
on all iterables.

>>> "abc".__iter__()

"We" are making it harder? Who's "we"? Python predates JavaScript by a
few years, and the latter language was spun up in less than two weeks
in order to create an 'edge' in the browser wars. So I don't think
anyone really planned for anyone to write multi-language code
involving Python and JS.
