At runtime it is equivalent to a plain dict. TypedDict creates a dictionary type that expects all of its instances to have a certain set of keys, with each key associated with a value of a consistent type. This expectation is not checked at runtime but is only enforced by typecheckers. Usage:: Point2D = TypedDict('Point2D', {'x': int, 'y': int, 'label': str}) a: Point2D = {'x': 1, 'y': 2, 'label': 'good'} # OK b: Point2D = {'z': 3, 'label': 'bad'} # Fails type check assert Point2D(x=1, y=2, label='first') == dict(x=1, y=2, label='first') The type info could be accessed via Point2D.__annotations__. TypedDict supports two additional equivalent forms:: Point2D = TypedDict('Point2D', x=int, y=int, label=str) class Point2D(TypedDict): x: int y: int label: str The latter syntax is only supported in Python 3.6+, while two other syntax forms work for 3.2+ cCs|S)zA normal positional argumentrtyper<rrrArgzsrIcCs|S)z*A positional argument with a default valuerrGrrr DefaultArgsrJcCs|S)zA keyword-only argumentrrGrrrNamedArgsrKcCs|S)z,A keyword-only argument with a default valuerrGrrrDefaultNamedArgsrLcCs|S)z*A *args-style variadic positional argumentrrHrrrVarArgsrNcCs|S)z*A **kwargs-style variadic keyword argumentrrMrrrKwArgsrOc@s eZdZdS)_DEPRECATED_NoReturnN)rrrCrrrrrPsrPcCs|Srr)rrrrtraitsrQcOsddS)NcSs|Srr)xrrrzmypyc_attr..r)attrsZkwattrsrrr mypyc_attrsrVc@seZdZddZddZdS)_FlexibleAliasClsAppliedcCs ||_dSrval)selfrYrrr__init__sz!_FlexibleAliasClsApplied.__init__cCs|jSrrXrZrrrr __getitem__sz$_FlexibleAliasClsApplied.__getitem__N)rrrCr[r]rrrrrWsrWc@seZdZddZdS)_FlexibleAliasClscCs t|dS)N)rWr\rrrr]sz_FlexibleAliasCls.__getitem__N)rrrCr]rrrrr^sr^c@seZdZddZdS)_NativeIntMetacCs t|tSr) isinstanceint)rinstrrrrDsz _NativeIntMeta.__instancecheck__N)rrrCrDrrrrr`sr`c@seZdZdefddZdS)i64rcCs|tk rt||St|Sr _sentinelrbrrRr@rrrr,s z i64.__new__NrrrCrfr,rrrrrdsrd) metaclassc@seZdZdefddZdS)i32rcCs|tk rt||St|Srrergrrrr,s z i32.__new__Nrhrrrrrjsrjc@seZdZdefddZdS)i16rcCs|tk rt||St|Srrergrrrr,s z i16.__new__Nrhrrrrrksrkc@seZdZdefddZdS)u8rcCs|tk rt||St|Srrergrrrr,s z u8.__new__Nrhrrrrrlsrla/A native fixed-width integer type when used with mypyc.
