Print("\n\nThe Area of square2 is:", square2.area()) Print("The Perimeter of square1 is:", square1.perimeter()) Print("The Area of square1 is:", square1.area()) Write a Python class, Square, and define two methods that return the square area and perimeter. The ClassName of the lion object is: Animal Print("The ClassName of the lion object is: ", lion._class_._name_) Property, we can access the object's class Name. Write a program that prints the class name using its object. Write a Python program to implement a stack data structure using class and objects, with push, pop, and traversal methods. Print("Teacher class's object all properties") By using the Pythonįunction on a class object, we can list out all the methods and attributes of the object or class. Write a Python program that lists all the default and custom properties of the class.Īll the properties of a class can be accessed through its object. Print("Is Staff a subclass of Teacher:", issubclass(Staff, Teacher)) Print("Is Teacher a subclass of Staff:", issubclass(Teacher, Staff)) To check if a class is a subclass of another, we can use the Python built-in Write a Python program that checks if one class is a subclass of another. Print("order1 > order2=", order1 > order2) Print("order1 + order2=", order1 + order2) For the + operator the dunder method is _add_() and for > its _gt_() To overload the operators for the class objects, we define the specific dunders method. Python custom class support operator overloading. Write a Python program that overloads the operator + and > for a custom class. #access private member outside the class will throw error #access private attribute inside the class _Classname_attributeName class Teacher(): Even after putting the double underscore before an attribute, it can still be accessed using the following syntax Still, we can follow the convention of putting double underscore _ before the variable name to make it private. In Python, there is no such thing as Private attributes or private members. Create a class Teacher with name, age, and salary attributes, where salary must be a private attribute that cannot be accessed outside the class. What would be the output of the following program? Write a program to create a class and, using the class instance, print all the writable attributes of that object.Īttribute that returns a dictionary of all the attributes available for that object. Write a program to create a child class Teacher that will inherit the properties from the parent class Staff. Keyword allows us to leave a block code without any body definition. Write a Program to create a valid empty class with the name Students, with no properties. Keyword, and to initialize the attribute during object creation, we define the Write a program to create a class by name Students, and initialize attributes like name, age, and grade while creating an object. Let us get started with the Python OOP exercise. Python class private and global properties Python class properties, methods, and attributes. In this Python object-oriented programming exercise, we will solve some of the common OOP problem statements that include the following topics. The same goes for Python object-oriented programming. Like other programming concepts, the best thing after learning any syntax is practicing the concept exercises and improving the skills. Its primary goal is to bring data and methods operating on that data together so that no other parts of the code can access that data. Works on objects that combine methods and properties. If you are a beginner learning Python, this object-oriented programming exercise will help you grasp OOP concepts quickly. Being an object-oriented programming language, Python supports OOP concepts - class, objects, inheritance, polymorphism, data encapsulation, and data abstraction.
