Python-based----object-oriented programming

There are several stages to object-oriented software development:

1. Object-oriented analysis (oriented, OOA)

2 Object-oriented design (oriented Design,ood)

3 Object-oriented programming (oriented Programming,oop)

4 Object-oriented testing (oriented Test,oot)

5 Object-oriented maintenance (object oriendted soft MAINTENANCE,OOSM)

Example 1

For the little white advice:

1. Object-oriented programming looks tall, so I should be programming to ensure that the entire class, so the written program must be a good program (object-oriented only for those with high scalability requirements of the scene)

2. A lot of people like to say the object-oriented three characteristics (where this comes from, encapsulation, polymorphism, inheritance?) There are too many loopholes, well, for the time being called the three major features, then I am in the object-oriented programming, I must let me define the class of the complete inclusion of these three features, so write is definitely a good program

Good boy, I said the Dragon 18 Palm has 18 palm, then every time you fight with people from the first hand to hit the 18th palm This just appears you will be, I have to 10,000 people you need to play 10000*18 palm right, silly fork

3. Class has a class property, instance has an instance property, so we define class when we must define a few class properties, what to do, then hard to think, define the more the better

This makes a serious mistake, the sooner the program object-oriented, the sooner the die, why object-oriented, because we want to combine the data with the function, the whole structure of the program is not out, or need to consider the problem you have not figured out a sorta, you began to object-oriented, which led to, you are there to do, Self-thought, defined a bunch of properties, the results are not used later, or can not figure out what should be defined, it has always wanted to, think about the crazy.

You have seen a company to develop a software, to start writing, it must be a frequent meeting to discuss the plan, see section Eighth

4. Since this is so troublesome, then I completely free, we do not use object-oriented programming, you Ah, you have a big, you can do it, silly fork.
