In Python, the __new__
method is a special method that is called to create a new instance of a class before it is initialized. It is a static method that takes the class as its first argument and returns a new instance of that class.
The __new__
method is responsible for creating the object, while the __init__
method initializes the object. The __new__
method is mainly used when you want to customize the object creation process or when dealing with immutable classes.
Here's an example to illustrate the usage of __new__
:
class MyClass:
def __new__(cls, args, *kwargs):
# Custom object creation logic
instance = super().__new__(cls)
# Additional customization if needed
return instance
def __init__(self, args, *kwargs):
# Object initialization code
# Creating an instance of MyClass
obj = MyClass()
In this example, the __new__
method is defined in the MyClass
class. It creates a new instance of the class using the super()
function and returns it. You can add your custom logic inside the __new__
method to modify the object creation process.
It's important to note that __new__
is a less commonly used method compared to __init__
. In most cases, you'll only need to define the __init__
method to initialize the object with the desired attributes.
I hope this guide helps you understand the __new__
method in Python!
