creating python classes code example

Example 1: python define class

class uneclasse():
  def __init__(self):
    pass
  def something(self):
    pass
xx = uneclasse()
xx.something()

Example 2: 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 3: python classes

class Student:
  def __init__(self, id, name, age):
    self.name = name
    self.id = id
    self.age = age
  
  def greet(self):
    print(f"Hello there.\nMy name is {self.name}")
    
  def get_age(self):
    print(f"I am {self.age}")
    
  def __add__(self, other)
  	return Student(
      self.name+" "+other.name,
      self.id + " "+ other.id,
      str(self.age) +" "+str(other.age))
    
p1 = Student(1, "Jay", 19)
p2 = Student(2, "Jean", 22)
p3 = Student(3, "Shanna", 32)
p4 = Student(4, "Kayla", 23)


result = p1+p3

Example 4: 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.

Example 5: creating python classes

class car:
  def __init__(self, model, color):
    self.model = model
    self.color = color
         
tesla = car("model 3", "black")

Example 6: creating python classes

class car:
  def __init__(self, model, color):
    self.model = model
    self.color = color
         
tesla = car("model 3", "black")
