how to declare a class in python code example

Example 1: how to make a class in python

class Person:
  def __init__(self, _name, _age):
    self.name = _name
    self.age = _age
   
  def sayHi(self):
    print('Hello, my name is ' + self.name + ' and I am ' + self.age + ' years old!')
    
p1 = Person('Bob', 25)
p1.sayHi() # Prints: Hello, my name is Bob and I am 25 years old!

Example 2: create and use python classes

class Mammal:
    def __init__(self, name):
        self.name = name

    def walk(self):
        print(self.name + " is going for a walk")


class Dog(Mammal):
    def bark(self):
        print("bark!")


class Cat(Mammal):
    def meow(self):
        print("meow!")


dog1 = Dog("Spot")
dog1.walk()
dog1.bark()
cat1 = Cat("Juniper")
cat1.walk()
cat1.meow()

Example 3: 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 4: 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()

Example 5: How to make a new class in python

#Use the class function and give the class a name
#next use the def __init__() to initilaize and give it some properties.
class Fruits():
  def __init__(self, name, colour, taste):
    self.name = name
    self.colour = colour
    self.taste = taste
#Now create an object by first calling the class
fruit1 = Fruits(apple, red, sweet)
print(fruit1.name)
#this will print the name which is apple
print(fruit1.colour)
#this will print the colour which is red
print(fruit1.taste)
#this will print the taste which is sweet
