What does Python _init_ and self do?
In a method like:
def method(self, something):
def __init__(?):
....
....
What does self do? What is it meant to be?
What does the __init__ method do and why is it necessary?
In python the self keyword is used to refer to the current object. However, if you have used other programming languages such as45 java and c++, it is very similar to the 'this' keyword in other languages.
The _init_ method is called the constructor, it is run whenever an Object of the current class is instantiated. It is used to set properties on an object when creating an object.
The self keyword allows us to refer to the properties of current object, to give you an example:
class Person:
def __init__(self, name):
self.name = name
david = Person("David")
print(david.name)
