Creating Objects With .__new__()
00:00
Object creation with __new__. When writing Python classes, you typically don’t need to provide your own implementation of the __new__ special method.
00:10
Most of the time, the base implementation from the built-in object class is sufficient to build an empty object of your current class. However, there are a few interesting use cases for this method.
00:22
For example, you can use __new__ to create subclasses of immutable types, such as int, float, tuple, and string.
00:29
In the following sections of the course, you’ll learn how to write custom implementations of __new__ in your classes. To do this, you’ll code a few examples that will give you an idea of when you might need to override this method. To get started, in the next section, you’ll see how to make use of the __new__ special method in your code to provide custom object creators.
