class Target:
    The Target defines the domain-specific interface used by the client code.

    def request(self) -> str:
        return "Target: The default target's behavior."

class Adaptee:
    The Adaptee contains some useful behavior, but its interface is incompatible
    with the existing client code. The Adaptee needs some adaptation before the
    client code can use it.

    def specific_request(self) -> str:
        return ".eetpadA eht fo roivaheb laicepS"

class Adapter(Target, Adaptee):
    The Adapter makes the Adaptee's interface compatible with the Target's
    interface via multiple inheritance.

    def request(self) -> str:
        return f"Adapter: (TRANSLATED) {self.specific_request()[::-1]}"

def client_code(target: "Target") -> None:
    The client code supports all classes that follow the Target interface.

    print(target.request(), end="")

if __name__ == "__main__":
    print("Client: I can work just fine with the Target objects:")
    target = Target()

    adaptee = Adaptee()
    print("Client: The Adaptee class has a weird interface. "
          "See, I don't understand it:")
    print(f"Adaptee: {adaptee.specific_request()}", end="\n\n")

    print("Client: But I can work with it via the Adapter:")
    adapter = Adapter()
