Signature de la fonction Required

def Required(*args, **kwds) 

Description

help(typing.Required)

A special typing construct to mark a key of a total=False TypedDict
    as required. For example:

        class Movie(TypedDict, total=False):
            title: Required[str]
            year: int

        m = Movie(
            title='The Matrix',  # typechecker error if key is omitted
            year=1999,
        )

    There is no runtime checking that a required key is actually provided
    when instantiating a related TypedDict.
