Description:
Hello,
In my opinion, some phrases on this page are not quite correct.
44.2.4. Composite Types
You say: '...Object (any object providing method __getattr__)...'
Actually, the object class provides the __getattribute__() method but not
the __getattr__() method.
See https://docs.python.org/3/reference/datamodel.html#object.__getattr__
44.2.5. Set-Returning Functions
1. You say: '...Sequence type (tuple, list, set)...'
Being an unordered collection, sets do not record element position or order
of insertion. Accordingly, sets do not support indexing, slicing, or other
sequence-like behavior.
See
https://docs.python.org/3/library/stdtypes.html#set-types-set-frozenset
2. You say: '...Iterator (any object providing __iter__ and next
methods)...'
Actually, the iterator objects must support the __next__() method.
See https://docs.python.org/3/glossary.html#term-iterator

Bogdan Grigorenko
