CSE 1224: Introduction to Computer Programming in Python Classes and objects - Write a simple class to keep track of addresses for a contact list.
Python programs are easy to understand as they have a clearly defined syntax and relatively simple structure. • Python is case-sensitive. For example
Python: Dynamic programming language which supports several different programing paradigms: Available as basic class in Python 2: object.
Class Definition Syntax: class ClassName: # Statement-1 . . . # Statement-N. Example : class Student: # A simple class. # attribute attr1 = "mamal".

Why Use Python? Traditional languages (C++ Java) evolved for large-scale programming. Emphasis on structure and discipline. Simple problems != simple
class Example: cnt=1 def __init__(selfnval=1): self n=nval def msg(self): print "Bo"+"o"*Example cnt+ "!"*self n >> e=Example() >> e n >> f=Example(2) >> f n 2 You can also de?ne the equivalentof Java’stoString method byde?ning a member functionnamed__str__(self) For example if we add def __str__(self): return "< d>" self n
In earlier Python versions only new-style classes could use Python’s newer versatile features like __slots__ descriptors properties __getattribute__() class methods and static methods object Any data with state (attributes or value) and de?ned behavior (methods)
Python Classes/Objects Python is an object oriented programming language. Almost everything in Python is an object, with its properties and methods. A Class is like an object constructor, or a "blueprint" for creating objects.
Python classes provide all the standard features of Object Oriented Programming: the class inheritance mechanism allows multiple base classes, a derived class can override any methods of its base class or classes, and a method can call the method of a base class with the same name. Objects can contain arbitrary amounts and kinds of data.
We can also create multiple objects from a single class. For example, In the above example, we have created two objects employee1 and employee2 of the Employee class. We can also define a function inside a Python class. A Python Function defined inside a class is called a method. In the above example, we have created a class named Room with:
It is a mixture of the class mechanisms found in C++ and Modula-3. Python classes provide all the standard features of Object Oriented Programming: the class inheritance mechanism allows multiple base classes, a derived class can override any methods of its base class or classes, and a method can call the method of a base class with the same name.
