4/20/2023 0 Comments Python class_init_() method takes the new object as its first argument, self. _init_(), takes the resulting object, along with the class constructor’s arguments. _new_(), which is responsible for creating and returning a new empty object. To run the first step, Python classes have a special method called. Initialize the new instance with an appropriate initial state.Create a new instance of the target class.This process runs through two separate steps, which you can describe as follows: You trigger Python’s instantiation process whenever you call a Python class to create a new instance. Understanding Python’s Instantiation Process _call_() special method, which has nothing to do with Python’s instantiation process. To make a class’s instance callable, you need to implement a. These are two different and unrelated topics. In Python, when you call a class as you did in the above example, you’re calling the class constructor, which creates, initializes, and returns a new object by triggering Python’s internal instantiation process.Ī final point to note is that calling a class isn’t the same as calling an instance of a class. In this example, you don’t need to pass any argument in the call because your class doesn’t take arguments yet. Then you create a new instance of SomeClass by calling the class with a pair of parentheses. Instead, the class’s body only contains a pass statement as a placeholder statement that does nothing. This class is currently empty because it doesn’t have attributes or methods. In this example, you define SomeClass using the class keyword. > # Call the class to construct an object > SomeClass () To better understand the examples and concepts in this tutorial, you should be familiar with object-oriented programming and special methods in Python. With this knowledge, you’ll be able to tweak the creation and initialization of objects in your custom Python classes, which will give you control over the instantiation process at a more advanced level.
