"Gradual Typing"| samgeo.codes
This PEP proposes a new special form, TypeIs, to allow annotating functions that can be used to narrow the type of a value, similar to the builtin isinstance(). Unlike the existing typing.TypeGuard special form, TypeIs can narrow the type in both the if...| Python Enhancement Proposals (PEPs)
Type hints introduced in PEP 484 can be used to specify type metadata for static type checkers and other third party tools. However, PEP 484 only specifies the semantics of nominal subtyping. In this PEP we specify static and runtime semantics of protoc...| Python Enhancement Proposals (PEPs)
PEP 484 defines the type Dict[K, V] for uniform dictionaries, where each value has the same type, and arbitrary key values are supported. It doesn’t properly support the common pattern where the type of a dictionary value depends on the string value of...| Python Enhancement Proposals (PEPs)

PEP 3107 introduced syntax for function annotations, but the semantics were deliberately left undefined. There has now been enough 3rd party usage for static type analysis that the community would benefit from a standard vocabulary and baseline tools w...| Python Enhancement Proposals (PEPs)
This PEP specifies an improved syntax for specifying type parameters within a generic class, function, or type alias. It also introduces a new statement for declaring type aliases.| Python Enhancement Proposals (PEPs)
