Python's __init__ constructor is one of the default methods used for instantiating objects from a class.
Examples
To define a class Cat and instantiate an object from it:
class Cat(): # This is constructor for python def __init__(self, name, age): self.name = name self.age = age # Teaching each cat how to meow def meow(self):
# Creating an instance my_cat representing my cat Roxasmy_cat = Cat("Roxas", 26)my_cat.meow()
I am a 26 year old Roxas
The self parameter must be provided and it must be provided first in the definition. However, when we instantiate an object, the self argument is automatically passed through hence it does not be provided.
Any variable prefixed with self is available to every method in the class. Hence, in the above example name and age variables are available to every method within class Cat. Variables that are associated with self (i.e. associated with the instance of the class) are referred to as attributes.
