How to Define and Use Class in Python

In this example we will show how to define and use class in Python.

2. Definition of Python Class

#!/usr/bin/python
# -*- coding: UTF-8 -*-

class Stu:

    def __init__(self, name, id):
        self.name = name
        self.id = id

    def displayInfo(self):
        print("Name: ", self.name, ", ID: ", self.id)

Notes:

The first method, the init() method, is a special method called a class constructor that is called when an instance of this class is created.
self is required as the first argument when defining the methods of the class. This is different from other languages like Java, C++, et al.

3. Use of Python Class

stu = Stu('Christina', 102)
stu.displayInfo()

Output:

Name: Christina, ID:  102
