In this example, we define a classStudentwith a parameterized constructor that accepts name, ID, and college details. These values are stored in instance variables. We then create an objectstudentwith specific values and call theDisplay_Details()method to print the student's information: classStud...
Here we have a instance variablenumwhich we are initializing in the constructor. The constructor is being invoked when we create the object of the class (obj in the following example). classDemoClass:# constructordef__init__(self):# initializing instance variableself.num=100# a methoddefread_...
Program to illustrate the constructor initialization classPerson:def__init__(self):print("Person Created[instantiate]")defgetPersonDetails(self):self.name=input("Enter Name : ")self.age=int(input("Enter Age : "))defprintDetails(self):print(self.name,self.age)P1=Person()P2=Person()P1.get...
The process continues with the instance initializer, .__init__(), which takes the constructor’s arguments to initialize the newly created object.To explore how Python’s instantiation process works internally, consider the following example of a Point class that implements a custom version of ...
classBike:name =""...# create objectbike1 = Bike() However, we can also initialize values using the constructors. For example, classBike:# constructor functiondef__init__(self, name =""):self.name = name bike1 = Bike() Here,__init__()is the constructor function that is called wh...

In the above example, we defined a class called "Cat". It has attributes 'name' and 'age', along with methods 'bark', 'get_age', and 'set_age'. The 'init' method is a special constructor method that initializes the attributes when a new instance of the class is created. ...
Thecalculate_age()method takes Student class (cls) as a first parameter and returns constructor by callingStudent(name, date.today().year - birthYear), which is equivalent toStudent(name, age). Example 2: Create Class Method Using classmethod() function ...
