python method class code example

Example 1: python class

class Animal(object): # Doesn't need params but put it there anyways.
    def __init__(self, species, price):
        self.species = species # Sets species name
        self.price = price # Sets price of it
    
    def overview(self): # A function that uses the params of the __init__ function
        print(f"This species is called a {self.species} and the price for it is {self.price}")

class Fish(Animal): # Inherits from Animal
    pass # Don't need to add anything because it's inherited everything from Animal
 
salmon = Fish("Salmon", "$20") # Make a object from class Fish
salmon.overview() # Run a function with it
dog = Animal("Golden retriever", "$400") # Make a object from class Animal
dog.overview() # Run a function with it

Example 2: 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
