object.__new__() takes exactly one argument (the type to instantiate)

and returns a new instance of that type. It is a static method that can be called on any class and is responsible for creating and returning a new instance of that class.
When a new instance of a class is created, Python automatically calls the __new__() method to create an empty object of that class. This method returns the newly created object, which is then passed to the __init__() method for initialization.
The __new__() method can be overridden to customize the creation of new instances. This is often done in cases where the default behavior of creating a new instance is not sufficient or when a subclass needs to create instances in a different way than its parent class.
In summary, the __new__() method is responsible for creating a new instance of a class, and it can be customized to provide alternative ways of creating instances.
