What is the purpose of the `__init__` method in Python classes?
The `__init__` method initializes a newly created object. It allows you to set initial values for attributes when an object is instantiated.
In Python, the __init__
method is a special method that initializes newly created objects. This method is called automatically when an object is instantiated from a class. The __init__
method allows you to set the initial values for the object's attributes and to execute any setup procedures required for the object.
Here’s a simple example:
class Car:
def __init__(self, make, model, year):
self.make = make
self.model = model
self.year = year
In this example, when you create a new instance of the Car
class, the __init__
method is called:
my_car = Car('Toyota', 'Corolla', 2021)
print(my_car.make) # Output: Toyota
The __init__
method can take additional parameters beyond self
, allowing you to customize the initialization process. This is particularly useful for enforcing required attributes and ensuring that objects are in a valid state upon creation. By defining an __init__
method, you enhance the usability and clarity of your classes.
