In Python, Method Resolution Order(MRO) is the order by whichPython looks for a method or attribute. First, the method or attribute is searched within a class, and then it follows the order we specified while inheriting. This order is also called the Linearization of a class, and a set ...
In this case, the method in the subclass overrides the method in the superclass. This concept is known as method overriding in Python. Example: Method Overriding classAnimal:# attributes and method of the parent classname =""defeat(self):print("I can eat")# inherit from AnimalclassDog(Anima...
Method Overriding: Subclasses can override superclass methods. When a method is called on an instance of the subclass, Python first looks for the method in the subclass. If not found, it looks for a method in the superclass. Single Inheritance: Python supports single inheritance, which means ...

I will instantiate this class into a new object calledc. Python has a built-infunction calleddir(),which returns a list of all the members of the classyou pass in. A class’s members are just the attributes and methods that make upthe class,including the special.__init__()method that...
