What is self in python?

Class based functions include a reference to self so that you can know which class instance called it. It represents the instance of the class. It is not a keyword in python. We can access attributes and methods of class by using self. It attaches the attributes with the given arguments.

E.g., 

class name():
 def __init__(self,ob1,ob2):
  self.ob1=ob1
  self.ob2=ob2
 def show(self):
  print(“ob1 is”, self.ob1)
  print(“ob2 is”, self.ob2)

Python class self constructor- Self is used to refer to a variable field within the class. 

E.g. 

class girl:
 def __init__(self, mary):
    self.name=mary
 def get_girl_name(self):
    return self.name

Important points to know about “self”:-

• Self is not a keyword in python. In place of self we can use other words also. But it is good to use self as it increases the readability of the program.
• Self makes it easy to differentiate between instance attributes and local variables. Python has no explicit variable declaration.
• Self is the first parameter of methods that represents the instance of the class in python.
