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 Python 2.7 and 3.2+ cC|S)zA normal positional argumentrtyper2rrrArgmr?cCr<)z*A positional argument with a default valuerr=rrr DefaultArgrr@rAcCr<)zA keyword-only argumentrr=rrrNamedArgwr@rBcCr<)z,A keyword-only argument with a default valuerr=rrrDefaultNamedArg|r@rCcCr<)z*A *args-style variadic positional argumentrr>rrrVarArgr@rEcCr<)z*A **kwargs-style variadic keyword argumentrrDrrrKwArgr@rFc@s eZdZdS)NoReturnN)rrr8rrrrrGs rGcCr<rr)rrrrtraitsrHcOsddS)NcSr<rr)xrrrszmypyc_attr..r)attrsZkwattrsrrr mypyc_attrsrLc@seZdZddZddZdS)_FlexibleAliasClsAppliedcCs ||_dSrval)selfrOrrr__init__s z!_FlexibleAliasClsApplied.__init__cCs|jSrrNrPrrrr __getitem__sz$_FlexibleAliasClsApplied.__getitem__N)rrr8rQrSrrrrrMs rMc@seZdZddZdS)_FlexibleAliasClscCs t|dS)N)rMrRrrrrSs z_FlexibleAliasCls.__getitem__N)rrr8rSrrrrrTs rTr)__doc__r rr rrrr$r>r!rr%rrr?rArBrCrErFrGrHrLrMrTZ FlexibleAliasrrrrs0   !
