Let's also talk about object-oriented and class, and also about object-oriented

Let's also talk about object-oriented and class, and also about object-oriented

There is no long story here, and only pseudo code is here

Today I want to cook, stir-fry two dishes, one is fried tomato with eggs and the other is fried cucumber with eggs. Now, what I want to do is buy food in the market first, and then cook

If the process is oriented, I will write it like this.

------------------- Process-oriented -----------------

Dish 1 = eggs

Dish 2 = tomato

Dish 3 = cucumber

 

Buy food 1

Buy food 2

Buy food 3

 

Cooking 1 (EGG)

Cut Vegetables 2 (cut tomatoes)

Finished Product 1 = sauteed dish 1 + dish 2

Cooking 1

Cut Vegetables 3 (cut cucumbers)

Finished 2 = sauteed 1 + 3

 

Print finished 1

Print finished product 2

------------------- Process-oriented -----------------

Obviously, this is complicated and not easy to grasp and allocate, so you can change all of them to the object-oriented method of functions.

---------------- Object-oriented --------------------

Def buy (dish ):

Pay

Return

 

Def (dish ):

Dish = pass (dish)

Return

 

Def cut (dish ):

If len (dish) = long:

Dish = slice (dish)

Else:

Dish = cut (dish)

Return

 

Def fried (dish 1, dish 2 ):

Finished Product = dish 1 + dish 2

Return finished product

 

If _ name _ = '_ main __':

Dish 1 = buy (eggs)

Food 2 = buy (tomato)

Food 3 = buy (cucumber)

Finished Product 1 = stir-fried (dish 1), cut (dish 2 ))

Finished Product 2 = stir-fried (dish 1), cut (DISH 3 ))

---------------- Object-oriented --------------------

Now I still think it is awkward. Since both finished product 1 and finished product 2 are hot-fried, the product can be directly classified as one type.

---------------- Object-oriented, add class --------------------

Def buy (dish ):

Pay

Return

 

Class cooking (object ):

Def _ init _ (self, dish 1, dish 2 ):

Self. Dish 1 = dish 1

Self. Dish 2 = dish 2

Def (self ):

Food = pass (self. Dish 1)

Return

Def cut (self ):

If len (dish) = long:

Dish = slice (dish)

Else:

Dish = cut (dish)

Return

Def (self ):

Finished Product = self. () + self. Cut ()

Return finished product

 

If _ name _ = '_ main __':

Dish 1 = buy (eggs)

Food 2 = buy (tomato)

Food 3 = buy (cucumber)

Finished Product 1 = sauteed food (dish 1, dish 2)

Print finished product 1. Stir Fry ()

Finished Product 2 = fried (dish 1, DISH 3)

Print finished product 2. Stir Fry ()

---------------- Object-oriented, add class --------------------

Next to the class, I talked to my friend two days ago and I gave this example. He said it was hard to understand. Is that true?
