python class instantiation

in python, classes are a fundamental concept of object-oriented programming (oop). they serve as blueprints for creating objects, which are instances of a class. in this tutorial, we'll explore how to instantiate (create) objects from a class and understand the basics of class instantiation.
a class is defined using the class keyword, followed by the class name and a colon. inside the class, you can define attributes (variables) and methods (functions) that describe the behavior and properties of the objects created from it.
to create an object (instance) from a class, you simply call the class like it's a function. this process is called instantiation. the result is a new instance of the class with its own set of attributes and methods.
in python, classes often have a special method called __init__, which serves as the constructor. it is called automatically when you create a new instance of the class and is used to initialize the object's attributes.
in the constructor, self represents the instance being created, and you can use it to set attributes for that instance. the param1 and param2 parameters are values you provide when creating the object.
instance variables are attributes specific to each instance of a class. they store data that can vary between objects. you can access and modify instance variables using the self keyword within class methods.
let's create a simple class called person to demonstrate class instantiation:
output:
in this example, we defined a person class with a constructor __init__, and we created two person objects (person1 and person2) with different attributes. we then called the introduce method on each object to display their information.
that's the basics of class instantiation in python. classes and objects are essential for structuring your code and modeling real-world concepts in your programs.
