#SUPER IN OOP PYTHON HOW TO#

By understanding how super() and _init_() work together, you can write more efficient and effective Python code. When used with _init_(), it allows you to call the parent class’s initialization logic while still adding your own functionality in the subclass’s _init_() method. In conclusion, the super() function in Python is a powerful tool for working with inheritance and OOP. When we create an instance of ChildClass and print out its instance variables, we get the following output: foo Then, we assign the arg3 argument to the instance variable self.arg3. In ChildClass, we call super()._init_(arg1, arg2) to call the _init_() method in the parent class and pass in the arg1 and arg2 arguments. We also have a ChildClass that inherits from ParentClass and has its own _init_() method that takes three arguments, arg1, arg2, and arg3. In this example, we have a ParentClass with an _init_() method that takes two arguments, arg1 and arg2, and assigns them to instance variables. arg3 = arg3 my_object = ChildClass ( 'foo', 'bar', 'baz' ) print ( my_object. arg2 = arg2 class ChildClass ( ParentClass ): def _init_ ( self, arg1, arg2, arg3 ): super (). This allows you to initialize the object using the parent class’s initialization logic, while still adding your own functionality in the subclass’s _init_() method.Ĭlass ParentClass : def _init_ ( self, arg1, arg2 ): self. When you use super() with _init_(), you’re essentially calling the _init_() method in the parent class from the subclass.

Now that we understand what _init_() and super() are, let’s talk about how to use them together. When we create an instance of ChildClass and call its my_method() method, we get the following output: Hello from the parent class! Then, we print “Hello from the child class!” to the console. In ChildClass, we call super().my_method() to call the my_method() method in the parent class. We also have a ChildClass that inherits from ParentClass and has its own my_method() method. In this example, we have a ParentClass with a my_method() method that prints “Hello from the parent class!” to the console. my_method () print ( 'Hello from the child class!' ) my_object = ChildClass () my_object. Class ParentClass : def my_method ( self ): print ( 'Hello from the parent class!' ) class ChildClass ( ParentClass ): def my_method ( self ): super ().
