‘personName’ and ‘personAge’ are two parameters to sent when a new object is to be created. You can also add additional parameters like the way it is shown in the example. Afterward, the first parameter must be ‘self’, as it passes a reference to the instance of the class itself. The constructor method starts with def _init_. We shall learn a greater role of constructor once we get to know about python inheritance. You may also print messages in the constructor to be confirmed whether the object has been created. Primarily, the constructor can be used to put values in the member variables.
PYTHON3 CLASS METHOD MAP CODE
Python class constructor is the first piece of code to be executed when you create a new object of a class. Python Class Constructor #defining constructor This part is optional as they can be initialized by the constructor. Every time we declare an object of this class, it will contain these two variables as its member. ‘name’ and ‘age’ are two member variables of the class ‘Person’. Python Class Variables #initializing the variables This line marks the beginning of class definition for class ‘Person’. The comments explain the next executable steps. As we know, the lines starting with “#” are python comments. This example is pretty much self-explanatory. #definition of the class starts hereĭef _init_(self, personName, personAge): Here’s the very basic structure of python class definition. Python class is the blueprint on which instances of the class are created. How would it be if you could declare a data type which itself contains more than one data types and can work with them with the help of any function? Python class gives you that opportunity.
If you remember, basic data types in python refer to only one kind of data at a time. Python Classīy this time, all of you should have already learned about Python Data Types. Python Classes and Objects are the core building blocks of Python programming language. Python is an object-oriented programming language.
