Which of the following is the correct way to instantiate an object belonging to the user-defined class Dog that has attributes of name and breed?

Question

pet = Dog("Spot", "Dalmatian")

dog = new Dog(self, "Oscar", "Lab")

pet = new Dog("Fido", "puppy", "Dalmatian")

dog = Dog(self, "Buddy", "Boxer")

Answer 1

The correct way to instantiate an object belonging to the user-defined class Dog, assuming the class takes two attributes (name and breed), is:

pet = Dog("Spot", "Dalmatian")

This line correctly creates an instance of the Dog class with "Spot" as the name and "Dalmatian" as the breed.

The other options are incorrect for the following reasons:

• dog = new Dog(self, "Oscar", "Lab"): In Python, we do not use the new keyword; that syntax is more common in other programming languages like Java.

• pet = new Dog("Fido", "puppy", "Dalmatian"): This option has three arguments, but the Dog class is supposed to take only the name and breed.

• dog = Dog(self, "Buddy", "Boxer"): Similar to the second option, the self parameter is used inside class methods to refer to the current instance; it should not be included when creating an instance of a class from outside.

Thus, the first option is the correct one.
