Represent an object in various string formsĪn official string representation of an object Returns a dictionary of attributes and values Modifies an existing attribute or creates a new attribute Returns the value of a specific attributeĬhecks whether an attribute exists or not List of Magic Methods and Their Uses Magic Method We can override them whenever we need them. All these magic methods are defined in the Python built-in classes. Magic methods are invoked indirectly by Python in the background. In this context, Dunder means Double Under (underscores). Magic methods are methods that have two prefix underscores and two suffix underscores. It can not modify/alter both the object’s and class’s state No decorator is decorator is decorator is neededĬan modify/alter both the object’s and class’s state It’s called by both object name and class name Instance Methods vs Class Methods vs Static Methods Instance MethodsĬalled by both object name and class name This makes finding the area of a square simpler and faster.

In the above code example, we do not need to create an object when we need to find an area of the square. Static methods are used to create utility functions.

Static methods are bound to the class just like class methods.

In the above code example, the static method dob_format() can be placed outside the class like a normal function but it makes more sense to define it inside a class because it helps the class in formatting the object’s date. They can work even outside the class but it makes more sense to keep them in the class. Static methods are mostly utility functions. Unlike Instance and Class methods, Static methods don’t take any implicit first arguments because it does not access or modify both the instance and class state. We accessed the method dob_format() using the class name as well. In the above code example, we added a static method dob_format() and an instance method get_dob() which calls the static method using the object address. Unlike other parameters, the value of the argument is provided directly by Python. The address of the object is passed as an argument to this parameter. Self Parameter in PythonĪll instance methods in a class have a parameter called self in their method definition. Instance methods are bound to the object and the attributes in the Instance methods can not be shared among objects. In the above code example, the method birthday accessed the class’s attribute no_of_students. Instance Methods can also access and modify the state/attributes of a class by using the self._class_ attribute. In the above code example, the method birthday accessed the object’s name and age attributes and altered the age attribute by incrementing its value. Using self, instance methods can access and alter the state/attributes of an object. The parameter self, similar to a pointer in C language, references to the current object of the class. All instance methods take the first parameter self and the value of self is automatically given by Python. We can notice that both these methods have a common parameter self in their class definition. _init_() is also called a magic method, we will learn about it in the next section.

We have called the birthday() method using the dot operator and the object name. In the above code example, we created two instance methods, _init_() method and birthday() method. 9 students of his class have sent Birthday wishes.
