I think islice should implement __length_hint__, though. As of 3.8.5 it doesn't.
And it could support __len__, and raise an Exception when the underlying iterable doesn’t support it. I know that itertools needs to support arbitrary iterable, but I do wish it provided more Sequence features when it could. islice, for instance, could support negative indexes when it is wrapping a Sequence. -CHB -- Christopher Barker, PhD Python Language Consulting - Teaching - Scientific Software Development - Desktop GUI and Web Development - wxPython, numpy, scipy, Cython
