When to use classes? [closed]

Before asking, make sure it's a less open question, please; but welcome to SO! :D

To answer your question in a simple way, classes are used when you want to make an abstraction of a real life object (That's where OOP comes from) , such as: A car, a person, a house...

An important thing to note is that Objects like this, their classes are used in the singular , not in the plural.

class Persona:
    ..atributos y métodos..

On a clase, Person in this case, you can define attributes of the class:

class Persona:

    def __init__(self, nombre, genero, edad):
        self._nombre = nombre
        self._genero = genero
        self._edad = edad

What goes in there is used __init__to initialize the attributes or any other variables of the class ; I guess you already know what parameters and arguments are, so I'll skip that part. selfit's like the this, but from Python, you can actually rename it to whatever you want but that's a horrible practice.

Then you can create instances of the class:

pepe = Persona('Pepe','H',22) #Creamos un objeto de la clase Persona, llamado Pepe, Hombre y de 22 años.

Then you can add more methods, attributes...

IN SUMMARY: The classes serve us to be able to take real life objects to an abstract or imaginary plane; they can have attributes (size, name, color...), methods (Modify something, delete something, or do something in general) and you create objects from them (I mean, you create a new instance of that class, with different attributes).

I highly recommend reading the Python documentation.

Luck ;)
