Real Python рџђќ Providing Multiple Constructors In Your Facebook In this step by step tutorial, you'll learn how to provide multiple constructors in your python classes. to this end, you'll learn different techniques, such as checking argument types, using default argument values, writing class methods, and implementing single dispatch methods. Unlike java, you cannot define multiple constructors. however, you can define a default value if one is not passed. self.city = city. if your signatures differ only in the number of arguments, using default arguments is the right way to do it.
Using Multiple Constructors In Your Python Classes Real Python Python does not support explicit multiple constructors, yet there are some ways to achieve multiple constructors. we use python's inbuilt init method to define the constructor of a class. it tells what will the constructor do if the class object is created. You can create multiple constructors in python by using optional arguments and branching logic in the . init () method. the built in @classmethod decorator allows you to define alternative constructors, using the class itself as the first argument.
