How object and class attributes work?
Before of we look objects, class and attributes, We come to inquire in the history.
All the concepts that we are saying about class methods atributes, belong to the OOP(Object Oriented Programming), it was maked by Alan kay in the 70s who had studied biology, which allowed parallelism between cell and programming.
I’m going to do is exemplify how a video of White balloon vs bacteria with music from linkin park in the background has to do with programming.
What is a class?
It’s a group of things that have something in common, in the video you could watch one class, it can be called cell. There are cell how the white balloon vs bacteria.
What’s a class attribute?
A attribute in programming is a variable, it allow at the class differenciate of others, a attribute is something that allows us to differentiate ourselves, in the video for example: the size, if is heterotrophic or autotrophic, color, etc..
What is a method?
A method is how a verb, it speaking in simples word, because the methods always perform a function in the example of the video is: Move, attack, defend, eat.
What’s an instance attribute?
A instance is one object or in the example of the video the cell, it maked already the which, we can access for modify yours features.
What are all the ways to create them and what is the Pythonic way of doing it?
If, We want make a class in python is very matter know about the before concepts more the concept constructor and destructor is similar to humans and cells in simples words is born and die.
What are the differences between class and instance attributes?
I going to answer through a example: You are in a lab
Class = Chromosomes of a bacterium with the we will can make it.
Instance attributes: Imagine that, We are inside of a laboratory and the bosses ask us a researching about the behavior of the White balloon vs Virus, we have the template for make our several cells, it can be Bacteria’s or White balloon, so we make our cell called object based in the template called class.
Code
Class Cells:
MyMethod __init__():
print(“Hello cell”)
Object above
Cell1 = Cells()
What are the advantages and drawbacks of each of them?
The advantages it can be best reusability of the code the which compress that we have make a lot of variables through the objects, the problem is with the class because we can modify.
Note: Is very matter we have clear the concept of encapsulation for understand how ensure our classe’s
How does Python deal with the object and class attributes using the __dict__?
Finally some tip matter for our class is how watch the attributes of instance is that each class the can watch through the dictionary the which contain the different behavior what will you have the class.
