Object-oriented programming is actually very simple--python object-oriented (elementary article)

In the teaching of Python, many students go to the object-oriented programming this piece began to circle, in order to help everyone better understand object-oriented programming and it can be used in their own development process, features this article.

Overview

• Process oriented: Write base code from top to bottom according to business logic

• Function: A function code is encapsulated in a function, it will not need to be repeated later, only the function can be called

• Object-oriented: classify and encapsulate functions to make development "faster, better and stronger ..."

Process-oriented programming is most easily accepted by beginners, it often uses a long code to achieve the specified function, the most common operation in the development process is to paste the copy, that is: Copy the previously implemented code block to the current function.

WHILE TRUE:    IF CPU utilization  >  90%:         #发送邮件提醒          Connect to mailbox Servers          send mail          Turn off connection      if  hard disk use space  > 90%:          #发送邮件提醒          Connect to a mailbox server           Send mail          close connection      if  memory consumption   > 80%:         #发送邮件提醒           connect to a mailbox server          send mail           Close Connection 

Over time, functional programming has been used to enhance the reusability and readability of code, and it has become:

def send mail (content) #发送邮件提醒 Connect mailbox server send mail close connection while True:if CPU utilization > 90%: Send mail (' CPU alarm ') if hard disk uses space > 90%: Send mail (' HDD alert ') if memory consumption > 80%: Send mail (' Memory alarm ')

Today we're going to learn a new way of programming: Object-oriented Programming (object Oriented Programming,oop, OO programming)
Note: Java and C # support object-oriented programming only, while Python is more flexible in that it supports object-oriented programming and functional programming

Creating Classes and objects

Object-oriented programming is a way of programming, which requires "classes" and "objects" to be implemented, so object-oriented programming is actually the use of "classes" and "objects".

A class is a template that can contain multiple functions and functions in a template.

Objects are instances created from templates that can execute functions in a class through an instance object
