Among other things, the module includes the following: * Generic, Protocol, and internal machinery to support generic aliases. All subscripted types like X[int], Union[int, str] are generic aliases. * Various "special forms" that have unique meanings in type annotations: Any, Never, ClassVar, Self, Concatenate, Unpack, and others. * Classes whose instances can be type arguments to generic classes and functions: TypeVar, ParamSpec, TypeVarTuple. * Public helper functions: get_type_hints, overload, cast, final, and others. * Several protocols to support duck-typing: SupportsFloat, SupportsIndex, SupportsAbs, and others. * Special types: NewType, NamedTuple, TypedDict. * Deprecated aliases for builtin types and collections.abc ABCs.

At runtime, functions marked this way should return a boolean. ``TypeGuard`` aims to benefit *type narrowing* -- a technique used by static type checkers to determine a more precise type of an expression within a program's code flow. Usually type narrowing is done by analyzing conditional code flow and applying the narrowing to a block of code. The conditional expression here is sometimes referred to as a "type predicate". Sometimes it would be convenient to use a user-defined boolean function as a type predicate. Such a function should use ``TypeGuard[...]`` or ``TypeIs[...]`` as its return type to alert static type checkers to this intention. ``TypeGuard`` should be used over ``TypeIs`` when narrowing from an incompatible type (e.g., ``list[object]`` to ``list[int]``) or when the function does not return ``True`` for all instances of the narrowed type. Using ``-> TypeGuard[NarrowedType]`` tells the static type checker that for a given function: 1. The return value is a boolean. 2. If the return value is ``True``, the type of its argument is ``NarrowedType``. For example:: def is_str_list(val: list[object]) -> TypeGuard[list[str]]: '''Determines whether all objects in the list are strings''' return all(isinstance(x, str) for x in val) def func1(val: list[object]): if is_str_list(val): # Type of ``val`` is narrowed to ``list[str]``. print(" ".join(val)) else: # Type of ``val`` remains as ``list[object]``. print("Not a list of strings!") Strict type narrowing is not enforced -- ``TypeB`` need not be a narrower form of ``TypeA`` (it can even be a wider form) and this may lead to type-unsafe results. The main reason is to allow for things like narrowing ``list[object]`` to ``list[str]`` even though the latter is not a subtype of the former, since ``list`` is invariant. The responsibility of writing type-safe type predicates is left to the user. ``TypeGuard`` also works with type variables.

Using ``-> TypeIs[NarrowedType]`` tells the static type checker that for a given function: 1. The return value is a boolean. 2. If the return value is ``True``, the type of its argument is the intersection of the argument's original type and ``NarrowedType``. 3. If the return value is ``False``, the type of its argument is narrowed to exclude ``NarrowedType``. For example:: from typing import assert_type, final, TypeIs class Parent: pass class Child(Parent): pass @final class Unrelated: pass def is_parent(val: object) -> TypeIs[Parent]: return isinstance(val, Parent) def run(arg: Child | Unrelated): if is_parent(arg): # Type of ``arg`` is narrowed to the intersection # of ``Parent`` and ``Child``, which is equivalent to # ``Child``. assert_type(arg, Child) else: # Type of ``arg`` is narrowed to exclude ``Parent``, # so only ``Unrelated`` is left. assert_type(arg, Unrelated) The type inside ``TypeIs`` must be consistent with the type of the function's argument; if it is not, static type checkers will raise an error. An incorrectly written ``TypeIs`` function can lead to unsound behavior in the type system; it is the user's responsibility to write such functions in a type-safe manner. ``TypeIs`` also works with type variables.

Example: Annotated[int, runtime_check.Unsigned] indicates to the hypothetical runtime_check module that this type is an unsigned int. Every other consumer of this type can ignore this metadata and treat this type as int. The first argument to Annotated must be a valid type. Details: - It's an error to call `Annotated` with less than two arguments. - Access the metadata via the ``__metadata__`` attribute:: assert Annotated[int, '$'].__metadata__ == ('$',) - Nested Annotated types are flattened:: assert Annotated[Annotated[T, Ann1, Ann2], Ann3] == Annotated[T, Ann1, Ann2, Ann3] - Instantiating an annotated type is equivalent to instantiating the underlying type:: assert Annotated[C, Ann1](5) == C(5) - Annotated can be used as a generic type alias:: type Optimized[T] = Annotated[T, runtime.Optimize()] # type checker will treat Optimized[int] # as equivalent to Annotated[int, runtime.Optimize()] type OptimizedList[T] = Annotated[list[T], runtime.Optimize()] # type checker will treat OptimizedList[int] # as equivalent to Annotated[list[int], runtime.Optimize()] - Annotated cannot be used with an unpacked TypeVarTuple:: type Variadic[*Ts] = Annotated[*Ts, Ann1] # NOT valid This would be equivalent to:: Annotated[T1, T2, T3, ..., Ann1] where T1, T2 etc. are TypeVars, which would be invalid, because only one type should be passed to Annotated. rzUAnnotated[...] should be used with at least two arguments (a type and an annotation).rz?Annotated[...] should not be used with an unpacked TypeVarTuplez$Annotated[t, ...]: t must be a type.TrsrN)rrrrrr;)rrrr4r>s r|rrswb 6{Q'( (!++01 1 0C CT BFVABZ H 6 ,,r~c|[U[5(a[USS5(d[SU-5eSUl[ 5UlURH=n[[XS55nU(dUR RU5 M=M?

Usage:: >>> class Point2D(TypedDict): ... x: int ... y: int ... label: str ... >>> a: Point2D = {'x': 1, 'y': 2, 'label': 'good'} # OK >>> b: Point2D = {'z': 3, 'label': 'bad'} # Fails type check >>> Point2D(x=1, y=2, label='first') == dict(x=1, y=2, label='first') True The type info can be accessed by calling inspect.get_annotations(Point2D), and via the Point2D.__required_keys__ and Point2D.__optional_keys__ frozensets. TypedDict supports an additional equivalent form:: Point2D = TypedDict('Point2D', {'x': int, 'y': int, 'label': str}) By default, all keys must be present in a TypedDict. It is possible to override this by using the NotRequired and Required special forms:: class Point2D(TypedDict): x: int # the "x" key must always be present (Required is the default) y: NotRequired[int] # the "y" key can be omitted This means that a Point2D TypedDict can have the "y" key omitted, but the "x" key must be present. Items are required by default, so the Required special form is not necessary in this example. In addition, the total argument to the TypedDict function can be used to make all items not required:: class Point2D(TypedDict, total=False): x: int y: int This means that a Point2D TypedDict can have any of the keys omitted. A type checker is only expected to support a literal False or True as the value of the total argument. True is the default, and makes all items defined in the class body be required. The Required special form can be used to mark individual keys as required in a total=False TypedDict. The ReadOnly special form can be used to mark individual keys as immutable for type checkers:: class DatabaseUser(TypedDict): id: ReadOnly[int] # the "id" key must not be modified username: str # the "username" key can be changed See PEPs 589, 655, and 705 for more information. Nrrrrz = TypedDict(z, {{}})`z{name} is deprecated and will be disallowed in Python {remove}.

This is an abstract, generic version of the return of open(). NOTE: This does not distinguish between the different possible classes (text vs. binary, read vs. write vs. read/write, append-only, unbuffered). The TextIO and BinaryIO subclasses below capture the distinctions between text vs. binary, which is pervasive in the interface.

The decorator can be applied to a function, class, or metaclass. Example usage with a decorator function:: @dataclass_transform() def create_model[T](cls: type[T]) -> type[T]: ... return cls @create_model class CustomerModel: id: int name: str On a base class:: @dataclass_transform() class ModelBase: ... class CustomerModel(ModelBase): id: int name: str On a metaclass:: @dataclass_transform() class ModelMeta(type): ... class ModelBase(metaclass=ModelMeta): ... class CustomerModel(ModelBase): id: int name: str The ``CustomerModel`` classes defined above will be treated by type checkers similarly to classes created with ``@dataclasses.dataclass``. For example, type checkers will assume these classes have ``__init__`` methods that accept ``id`` and ``name``. The arguments to this decorator can be used to customize this behavior: - ``eq_default`` indicates whether the ``eq`` parameter is assumed to be ``True`` or ``False`` if it is omitted by the caller. - ``order_default`` indicates whether the ``order`` parameter is assumed to be True or False if it is omitted by the caller. - ``kw_only_default`` indicates whether the ``kw_only`` parameter is assumed to be True or False if it is omitted by the caller. - ``frozen_default`` indicates whether the ``frozen`` parameter is assumed to be True or False if it is omitted by the caller. - ``field_specifiers`` specifies a static list of supported classes or functions that describe fields, similar to ``dataclasses.field()``. - Arbitrary other keyword arguments are accepted in order to allow for possible future extensions. At runtime, this decorator records its arguments in the ``__dataclass_transform__`` attribute on the decorated object. It has no other runtime effect.

Usage:: class Base: def method(self) -> None: pass class Child(Base): @override def method(self) -> None: super().method() When this decorator is applied to a method, the type checker will validate that it overrides a method or attribute with the same name on a base class. This helps prevent bugs that may occur when a base class is changed without an equivalent change to a child class. There is no runtime checking of this property. The decorator attempts to set the ``__override__`` attribute to ``True`` on the decorated object to allow runtime introspection. See PEP 698 for details.
