[issue28073] Update documentation about None vs type(None) in typing
New submission from Michael Lee: For some reason, the section of the typing docs about Optional stated that Optional[T] was equivalent to Union[T, type(None)]. While this is true, it's somewhat inconsistent and potentially confusing since everywhere else in the docs, we just use None. This patch modifies that line to use Union[T, type(None)] instead, and moves the line explaining that None is special-cased to mean type(None) to the first usage of None as a type within the docs. -- assignee: docs@python components: Documentation files: update-none-vs-type-none.patch keywords: patch messages: 275718 nosy: docs@python, gvanrossum, michael0x2a priority: normal severity: normal status: open title: Update documentation about None vs type(None) in typing versions: Python 3.5, Python 3.6, Python 3.7 Added file: http://bugs.python.org/file44542/update-none-vs-type-none.patch ___ Python tracker <http://bugs.python.org/issue28073> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue28049] Add documentation for typing.Awaitable and friends
New submission from Michael Lee: This patch adds documentation for Awaitable, AsyncIterable, and AsyncIterator to the typing module, mostly linking to the corresponding class in collections.abc. It also briefly clarifies the documentation on generators to explain that you may use either Iterable or Iterator as the return type of a generator. -- assignee: docs@python components: Documentation files: document-awaitable.patch keywords: patch messages: 275379 nosy: docs@python, gvanrossum, michael0x2a priority: normal severity: normal status: open title: Add documentation for typing.Awaitable and friends versions: Python 3.5, Python 3.6, Python 3.7 Added file: http://bugs.python.org/file44507/document-awaitable.patch ___ Python tracker <http://bugs.python.org/issue28049> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue27905] Add documentation for typing.Type

[issue27723] Document typing.Text and typing.AnyStr
New submission from Michael Lee: This patch documents typing.Text and typing.AnyStr. I decided against creating a new top-level section to document Text/AnyStr mainly because it seems like how exactly str/bytes/unicode is handled by mypy and described in PEP 484 might be changing sometime in the future and didn't want to add text that would need to be changed later on -- I'm not sure if that was the right call or not. -- assignee: docs@python components: Documentation files: document-text-and-anystr.patch keywords: patch messages: 272286 nosy: docs@python, gvanrossum, michael0x2a priority: normal severity: normal status: open title: Document typing.Text and typing.AnyStr versions: Python 3.5, Python 3.6 Added file: http://bugs.python.org/file44062/document-text-and-anystr.patch ___ Python tracker <http://bugs.python.org/issue27723> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue27688] Expand documentation about Any in the typing module
New submission from Michael Lee: This patch updates the section about `Any` in the typing module. Previously, that section was relatively sparse and didn't seem to do a very good job of helping the reader understand what the distinction between `Any` and `object` is.

[issue27644] Expand documentation about type aliases and NewType in the typing module
New submission from Michael Lee: This is a patch to update the documentation on the typing module. It expands the section on type aliases and adds a section on [NewType][0]. Since support for NewType was [recently added][1] to mypy, it seemed like a prudent time to update the docs to describe this new feature. The section on type aliases was mainly expanded because the distinction between type aliases and NewType could be potentially confusing, so adding extra clarification seemed like a good idea.

[issue27402] Sequence example in typing module documentation does not typecheck
Michael Lee added the comment: Whoops, forgot the link to the error in the docs: https://docs.python.org/3/library/typing.html#typing.List -- ___ Python tracker <http://bugs.python.org/issue27402> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue27402] Sequence example in typing module documentation does not typecheck
New submission from Michael Lee:
In the documentation for the `typing` module, the [entry for the `List`
type][0] uses the following example to help demonstrate when to use `Sequence`
vs `List`:
T = TypeVar('T', int, float)
def vec2(x: T, y: T) -> List[T]:
return [x, y]
def slice__to_4(vector: Sequence[T]) -> List[T]:
return vector[0:4]
However, the `slice__to_4` function does not actually typecheck since there's
no guarantee that a slice of a sequence will return a `List`. For example the
vector could be a numpy array or a custom subclass of
`collections.abc.Sequence` with an unusual `__getitem__`. (Mypy correctly
catches this error and complains about an "Incompatible return value type").
The documentation should probably be updated to use an example that _does_
typecheck, though I'm not sure what exactly that example might look like? Maybe
replace `slice__to_4` with something like this?
def keep_positives(vector: Sequence[T]) -> List[T]:
return [item for item in vector if item > 0]
