How do I use __init__ in Python?

Can you explain how to use the init method in Python?

Sure! The init method is a special method in Python classes that initializes new objects. It's called when you create a new instance of a class.

What parameters can I pass to init?

You can pass any parameters you want to init. Typically, you'll pass attributes that you want to set when creating an object.

Can you give me an example of a class using init?

Of course! 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 if I don't define init in my class?

If you don't define init, Python will provide a default constructor that doesn't do anything. You won't be able to initialize attributes at the time of object creation.
