Course Introduction:How to use the __new__() function to create an object instance in Python The __new__() function is a special method built into Python that is used to create object instances. Unlike the __init__() method, the __new__() method is called before the object is instantiated. It is responsible for creating the object and returning an instance of the object. In Python, whenever an object instance is created, it is actually done by calling the __new__() method of the class. __new__()

Course Introduction:Preface What is the function of the __new__ method of the class constructor in Python? Some method names and attribute names in Python classes are preceded and followed by __ double underscores. Such methods and attributes usually belong to Python's special methods and attributes. Implement special functions by overriding these methods or calling them directly. Today let’s talk about the application scenarios of the construction method __new__ in actual programs. We know the common initialization __init__ method and can rewrite it to implement the initialization logic we want. Recently, we have encountered a type of problem in the actual business development process, such as the implementation of the data resource loading and caching mechanism. The construction method in the magic method is used, among which __init__() and __new__ are the constructors of the object.

Course Introduction:Methods defined within a Python class and ending with _ _ xx _ _ are all built-in methods of the class, also called magic methods. The built-in methods of the class will be automatically triggered when certain conditions are met. Here we focus on explaining __init__ and __new__, which are related to instance creation. Brief description __init____init__(self): We are relatively familiar with this method. It is the default initialization method in python classes, that is, the method that will be executed when a class is instantiated. Detailed explanation of __new____new__ method overriding is very fixed, usually as follows: def __new__(cls): return super().__n
