Python built-ins worth learning (2019)

Tuple, list, and numpy array are all different isinstance()’s, so I’d have to call them all out. len() avoids that.

This is incorrect, because you can generally do this for sequence types:

    isinstance(items, Sequence)

Or perhaps:

    isinstance(items, Iterable)  # works with numpy arrays

Or, equivalent to using len() for type checking, you could do:

    isinstance(items, Sized)
