what is python class code example

Example 1: python classes

class Box(object): #(object) ending not required
  def __init__(self, color, width, height): # Constructor: These parameters will be used upon class calling(Except self)
    self.color = color # self refers to global variables that can only be used throughout the class
    self.width = width
    self.height = height
    self.area = width * height
  def writeAboutBox(self): # self is almost always required for a function in a class, unless you don't want to use any of the global class variables
    print(f"I'm a box with the area of {self.area}, and a color of: {self.color}!")

greenSquare = Box("green", 10, 10) #Creates new square
greenSquare.writeAboutBox() # Calls writeAboutBox function of greenSquare object

Example 2: class python

class MyClass(object):
  def __init__(self, x):
    self.x = x

Example 3: python class

class Person:
  def __init__(self, name, age):
    self.name = name
    self.age = age
  def myfunc(self):
    print("Hello my name is " + self.name +".")

p1 = Person("Victor", 24)
p1.myfunc()

Example 4: how to declare a class in python

class ClassName(object): #"(object)" isn't mandatory unless this class inherit from another
  	def __init__(self, var1=0, var2):
    
    	#the name of the construct must be "__init__" or it won't work
    	#the arguments "self" is mandatory but you can add more if you want 
    	self.age = var1
    	self.name = var2
    
    	#the construct will be execute when you declare an instance of this class
    
  	def otherFunction(self):
    	
        #the other one work like any basic fonction but in every methods,
    	#the first argument (here "self") return to the class in which you are

Example 5: class python

class Person:
  def __init__(self, name, age):
    self.name = name
    self.age = age

p1 = Person("John", 36)

p1.age = 40

print(p1.age)
---------------------------------------------------------------
40

Example 6: what is a class in python

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.
