为了让 Dog 类的构造函数能正确地调用其父类 Animal 的构造方法，横线线处应填入（ ）。
class Animal:
def __init__(self, name: str):
self.name = name
print("Animal created")
def speak(self) -> None:
print("Animal speaks")
class Dog(Animal):

def speak(self) -> None:

if __name__ == "__main__":
animal: Animal = Dog("Rex", "Labrador")
animal.speak()def __init__(self, name: str, breed: str):
super().__init__(name)
self.breed = breeddef __init__(self, name: str, breed: str):
