A class is a block of code that holds various functions. Because they
are located inside a class they are named methods but mean the samne
thing. In addition variables that are stored inside a class are named
attributes. The point of a class is to call the class later allowing you
to access as many functions or (methods) as you would like with the same
class name. These methods are grouped together under one class name due
to them working in association with eachother in some way.
#example
# To create a simple class:
class Shape:
def __init__():
print("A new shape has been created!")
pass
def get_area(self):
pass
# To create a class that uses inheritance and polymorphism
# from another class:
class Rectangle(Shape):
def __init__(self, height, width): # The constructor
super.__init__()
self.height = height
self.width = width
def get_area(self):
return self.height * self.widthcreating python classes
class car:
def __init__(self, model, color):
self.model = model
self.color = color
tesla = car("model 3", "black")why should i use classes in python

Classes are essential in OOP.
A good reason to use classes is to make your code structured and organised.
Furthermore it is easy to import functions when they are part of a class since you can just import the class.
Classes provide methods that are useful such as the __repr__ method which allows you to represent an object by a string.
Classes allow for access control (encapsulation) by using the underscore character.Copyright © 2021 Codeinu
