We cant overload constructors or methods in Python. Whenever we try to instantiate an object init() is automatically invoked by python to initialize members of an object. In the above example, the cls argument of the factory method refers to the class itself. Pythons constructor: init is the first method of a class. This method is the most pythonic way of overloading a constructor. We can use them to implement the concept of constructor overloading in Python. When used in overloading, such functions are called factory methods. Such methods can be accessed by the class itself and via its instances. Like any other object-oriented programming language applied for the development of a system or web-based application, Python allows. The decorator allows the function to be accessible without instantiating a class. Destructor in a program plays the role of reversing the operations performed by the constructor used for clearing the object of the class created by the constructor program. Creating a constructor : We need to define a method called init () inside our class. Syntax of a constructor : def init (self): body. In Python, a constructor is invoked automatically when we create an object. Use the Decorators to Overload a Constructor in Python The purpose of defining a constructor is, it provides state and uniqueness to the object. This method is similar to the previous example. We can also overload a constructor based on the number of arguments provided. The construct is overloaded to give the output based on the type of arguments provided. One is a string, and the other is an integer. In the above example, we have two types of parameters in the constructor. We can overload a constructor by declaring multiple conditions, with every condition based on a different set of arguments. Using Multiple Arguments to Overload Constructors in PythonДЇunction overloading refers to having different functions with the same name with different types of parameters. We will discuss these methods in this article. But there are some alternative ways to overload a constructor in Python. When multiple constructors are provided in the class, the latest one overrides the previous one. Multiple constructors are not directly supported in Python. While using different parameters, we can trigger different constructors. Multiple constructors help in customizing our custom class accordingly to its parameters.
