python class attributes code example

Example 1: declare class python

# 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.width

Example 2: class attributes in python

class MyClass:
  # Class attributes are defined outside of constructor
  class_attr = 0
  
  def __init__(self, inst):
    # Instance attributes are defined in the constructor
    self.instance_attr = inst
    
obj = MyClass(1)
print(obj.class_attr) # outputs 0
print(obj.instance_attr) # outputs 1
print(MyClass.class_attr) # outputs 0
print(MyClass.instance_attr) # raises AttributeError

Example 3: python class

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

    def speak(self):
        print("Hi I'm ", self.name, 'and I am', self.age, 'Years Old')

JUB0T = Dog('JUB0T', 55)
Friend = Dog('Doge', 10)
JUB0T.speak()
Friend.speak()

class Vehicle:
    def __init__(self, brand, model, type):
        self.brand = brand
        self.model = model
        self.type = type
        self.gas_tank_size = 14
        self.fuel_level = 0

    def fuel_up(self):
        self.fuel_level = self.gas_tank_size
        print('Gas tank is now full.')

    def drive(self):
        print(f'The {self.model} is now driving.')

obj = Vehicle("Toyota", "Carola", "Car")
obj.drive()

Example 5: how to assign a variable to a class in python

class Shark:
    animal_type = "fish"
    location = "ocean"
    followers = 5

new_shark = Shark()
print(new_shark.animal_type)
print(new_shark.location)
print(new_shark.followers)
