Defining a Dog Class that Inherits from the Pet Class and Extends the __str__ Special Method

How can you define a Dog class that inherits from the Pet class and extends the __str__ special method?

Provide an example code snippet along with an explanation.

Answer:

To define a Dog class that inherits from the Pet class and extends the __str__ special method, you can use the following code example:

Code Example:

In order to define a Dog class that inherits from the Pet class and extends the __str__ special method, you can use the following Python code:

```python class Dog(Pet): def __init__(self, name, weight): super().__init__(name) self.weight = weight def __str__(self): return super().__str__() + " and it's a dog" ```

Explanation:

The provided code snippet defines a Dog class that inherits from the Pet class. The __init__ method takes the name and weight of the dog as parameters. The __str__ method appends the extra string " and it's a dog" to the output of the parent class's __str__ method.

By extending the __str__ method in the Dog class, you can customize the string representation of Dog instances to include additional information beyond just the name, in this case, indicating that it is a dog.
