# class = factory that makes humans

class human:
    """"
#:    The __init__ method in the human class is a special method in Python known as a constructor. 
##    It is automatically called when a new instance (object) of the class is created. 
##    The primary purpose of the __init__ method is to initialize the attributes of the object with the values provided when the object is instantiated.

#  @ In the context of the human class:
#      - The __init__ method takes three parameters: self, name, and age.
#      - self refers to the instance of the class that is being created.
#      - name and age are the values that are passed when creating a new human object.
#      - Inside the __init__ method, the attributes _name and _age of the instance are set to the values of name and age, respectively. 
#      - This allows each human object to have its own unique name and age.

    def __init__(self, name, age): # so self is not an error here self in python refers to the human that we have created here

#: WELL:- the human class has 3 methods or "functions"
## 1. __init__ method: This is a special method in Python known as a constructor
## 2. __str__ method: This method is used to return a string representation of the message
## 3. __repr__ method: This method is used to return a string representation of the message(for google colab only)
