The `__init__` function in Python is a special method called a constructor. It is automatically invoked when an instance of a class is created. Its primary purpose is to initialize the object’s attributes.

Here’s how it works:

Definition: It starts with `def __init__(self, …)` and includes the `self` parameter, which refers to the instance being created.

Initialization: You can pass additional parameters to `__init__` to set initial values for the object’s attributes.

Example

class Person:

def __init__(self, name, age):

self.name = name

self.age = age

p1 = Person(“Alice”, 30)

print(p1.name) # Output: Alice

print(p1.age) # Output: 30

In this example, the `__init__` method initializes `name` and `age` attributes for the `Person` class. When creating an instance (`p1`), `”Alice”` and `30` are passed as arguments, setting the initial state of the object. The `__init__` method ensures that these attributes are properly set when the object is created.
