What are constructors in Python's object-oriented programming?

What are constructors in Python's object-oriented programming?

Constructors in Python are special methods called when an object is created. They initialize the object's attributes.

Can you show me an example of a constructor in a Python class?

Sure! Here's a simple example:

class Dog:
    def __init__(self, name, age):
        self.name = name
        self.age = age

my_dog = Dog('Buddy', 3)
print(my_dog.name)  # Output: Buddy

What is the purpose of the __init__ method?

The __init__ method is the constructor in Python. It initializes the object's attributes when an instance is created.

Can constructors have default parameters?

Yes, constructors can have default parameters. For example:

class Cat:
    def __init__(self, name='Kitty', age=2):
        self.name = name
        self.age = age
