At large scale, the structure of the module is following: * Imports and exports, all public names should be explicitly added to __all__. * Internal helper functions: these should never be used in code outside this module. * _SpecialForm and its instances (special forms): Any, NoReturn, ClassVar, Union, Optional * Two classes whose instances can be type arguments in addition to types: ForwardRef and TypeVar * The core of internal generics API: _GenericAlias and _VariadicGenericAlias, the latter is currently only used by Tuple and Callable. All subscripted types like X[int], Union[int, str], etc., are instances of either of these classes. * The public counterpart of the generics API consists of two classes: Generic and Protocol (the latter is currently private, but will be made public after PEP 544 acceptance). * Public helper functions: get_type_hints, overload, cast, no_type_check, no_type_check_decorator. * Generic aliases for collections.abc ABCs and few additional protocols. * Special types: NewType, NamedTuple, TypedDict (may be added soon). * Wrapper submodules for re and io related types.

An annotation wrapped in ClassVar indicates that a given attribute is intended to be used as a class variable and should not be set on instances of that class. Usage:: class Starship: stats: ClassVar[Dict[str, int]] = {} # class variable damage: int = 10 # instance variable ClassVar accepts only types and cannot be further subscribed. Note that ClassVar is not a class itself, and should not be used with isinstance() or issubclass(). a'Union type; Union[X, Y] means either X or Y. To define a union, use e.g. Union[int, str]. Details: - The arguments must be types and there must be at least one. - None as an argument is a special case and is replaced by type(None). - Unions of unions are flattened, e.g.:: Union[Union[int, str], float] == Union[int, str, float] - Unions of a single argument vanish, e.g.:: Union[int] == int # The constructor actually returns int - Redundant arguments are skipped, e.g.:: Union[int, str, int] == Union[int, str] - When comparing unions, the argument order is ignored, e.g.:: Union[int, str] == Union[str, int] - You cannot subclass or instantiate a union. - You can use Optional[X] as a shorthand for Union[X, None]. zEOptional type.

Usage:: T = TypeVar('T') # Can be anything A = TypeVar('A', str, bytes) # Must be str or bytes Type variables exist primarily for the benefit of static type checkers. They serve as the parameters for generic types as well as for generic function definitions. See class Generic for more information on generic types. Generic functions work as follows: def repeat(x: T, n: int) -> List[T]: '''Return a list containing n references to x.''' return [x]*n def longest(x: A, y: A) -> A: '''Return the longest of two strings.''' return x if len(x) >= len(y) else y The latter example's signature is essentially the overloading of (str, str) -> str and (bytes, bytes) -> bytes. Also note that if the arguments are instances of some subclass of str, the return type is still plain str. At runtime, isinstance(x, T) and issubclass(C, T) will raise TypeError. Type variables defined with covariant=True or contravariant=True can be used to declare covariant or contravariant generic types. See PEP 484 for more details. By default generic types are invariant in all type variables. Type variables can be introspected. e.g.: T.__name__ == 'T' T.__constraints__ == () T.__covariant__ == False T.__contravariant__ = False A.__constraints__ == (str, bytes) Note that only type variables defined in global scope can be pickled. )rZ __bound____constraints__ __covariant____contravariant__NF)bound covariant contravariantc s||_|r|rtdt||_t||_|r>|dk r>td|rVt|dkrVtddtfdd|D|_|rt |d|_ nd|_ yt dj d d }Wnttfk rd}YnX|d kr||_dS) Nz"Bivariant types are not supported.z-Constraints cannot be combined with bound=...rtz"A single constraint is not allowedz:TypeVar(name, constraint, ...): constraints must be types.c3s|]}t|VqdS)N)rT)r^r_)rPrRrSr#sz#TypeVar.__init__..zBound must be a type.rZ__main__typing)rZ ValueErrorboolrrrLrprfrrTrsys _getframe f_globalsgetAttributeErrorrV)rrrrrZ constraintsZdef_modrR)rPrSrs(    zTypeVar.__init__cCs&|jr d}n|jrd}nd}||jS)N+-~)rrrZ)rprefixrRrRrSr/s zTypeVar.__repr__cCs|jS)N)rZ)rrRrRrSr8szTypeVar.__reduce__)rZrVrWrrrrrrRrRrRrSrs * ) rhrfdictru frozensetdeque defaultdictrGr7cCs|do|dS)N__) startswithendswith)attrrRrRrS _is_dunderSsrcseZdZdZddddddZedd Zd d Zd d ZddZ ddZ ddZ ddZ ddZ fddZddZddZddZZS) rJaThe central part of internal API.

TypeError is raised if the argument is not of a type that can contain annotations, and an empty dictionary is returned if no annotations are present.

The subscription syntax must always be used with exactly two values: the argument list and the return type. The argument list must be a list of types or ellipsis; the return type must be a single type. There is no syntax to indicate optional or keyword arguments, such function types are rarely used as callback types. F)rra@Tuple type; Tuple[X, Y] is the cross-product type of X and Y. Example: Tuple[T1, T2] is a tuple of two elements corresponding to type variables T1 and T2. Tuple[int, float, str] is a tuple of an int, a float and a string. To specify a variable-length tuple of homogeneous type, use Tuple[T, ...]. )raA special construct usable to annotate class objects. For example, suppose we have the following classes:: class User: ... # Abstract base for User classes class BasicUser(User): ... class ProUser(User): ... class TeamUser(User): ... And a function that takes a class argument that's a subclass of User and returns an instance of the corresponding class:: U = TypeVar('U', bound=User) def new_user(user_class: Type[U]) -> U: user = user_class() # (Here we could write the user object to a database) return user joe = new_user(BasicUser) At this point the type checker knows that joe has type BasicUser. c@s&eZdZdZdZeedddZdS)r.z(An ABC with one abstract method __int__.rR)returncCsdS)NrR)rrRrRrS__int__ szSupportsInt.__int__N)rZrVrWrrrintr2rRrRrRrSr.sc@s&eZdZdZdZeedddZdS)r-z*An ABC with one abstract method __float__.rR)r1cCsdS)NrR)rrRrRrS __float__szSupportsFloat.__float__N)rZrVrWrrrfloatr4rRrRrRrSr-sc@s&eZdZdZdZeedddZdS)r,z,An ABC with one abstract method __complex__.rR)r1cCsdS)NrR)rrRrRrS __complex__szSupportsComplex.__complex__N)rZrVrWrrrcomplexr6rRrRrRrSr,sc@s&eZdZdZdZeedddZdS)r+z*An ABC with one abstract method __bytes__.rR)r1cCsdS)NrR)rrRrRrS __bytes__'szSupportsBytes.__bytes__N)rZrVrWrrrbytesr8rRrRrRrSr+#sc@s&eZdZdZdZeedddZdS)r*zMAn ABC with one abstract method __abs__ that is covariant in its return type.rR)r1cCsdS)NrR)rrRrRrS__abs__0szSupportsAbs.__abs__N)rZrVrWrrrr+r:rRrRrRrSr*,sc@s*eZdZdZdZedeedddZdS) r/zOAn ABC with one abstract method __round__ that is covariant in its return type.rRr)ndigitsr1cCsdS)NrR)rr;rRrRrS __round__9szSupportsRound.__round__N)r) rZrVrWrrrr3r+r<rRrRrRrSr/5sc svdfdd|D}t|dd|D}t||_|_ytdjdd|_ Wnt t fk rpYnX|S)NzDNamedTuple('Name', [(f0, t0), (f1, t1), ...]); each t must be a typecsg|]\}}|t|fqSrR)rT)r^nr_)rPrRrSra@sz!_make_nmtuple..cSsg|] \}}|qSrRrR)r^r=r_rRrRrSraAsrrZr) r namedtupler6r  _field_typesrrrrrVrr)rrXnm_tplrR)rPrS _make_nmtuple>srA) rrr__getnewargs___fields_field_defaultsr?_make_replace_asdictZ_source)rVrZr cseZdZfddZZS)NamedTupleMetac s|ddrt||||S|di}t||}g}i}xP|D]H}||krn||} || | ||<qF|rFtdj|d| dqFWt ||j_ t ||j_||_xD|D]<} | tkrtd| q| tkr| |jkrt|| || qW|S)NrFr zXNon-default namedtuple field {field_name} cannot follow default field(s) {default_names}z, ) field_nameZ default_namesz&Cannot overwrite NamedTuple attribute )rrrrArrbrLrrr$rr6r rfrrD _prohibitedrrcrCr) rqtypenamernsrXr@rZ defaults_dictrIZ default_valuekey)rrRrSrVs0       zNamedTupleMeta.__new__)rZrVrWrrrRrR)rrSrHTsrHc@s"eZdZdZdZddZde_dS)r9a4Typed version of namedtuple. Usage in Python versions >= 3.6:: class Employee(NamedTuple): name: str id: int This is equivalent to:: Employee = collections.namedtuple('Employee', ['name', 'id']) The resulting class has extra __annotations__ and _field_types attributes, giving an ordered dict mapping field names to types. __annotations__ should be preferred, while _field_types is kept to maintain pre PEP 526 compatibility. (The field names are in the _fields attribute, which is part of the namedtuple API.)
