Explanation of Solution

“__init__” method:

  • • It is a special method in Python class.
  • • This method is automatically executed when the instance of the class is created in the memory.
  • • This method is most commonly known as the initializer method.
  • • This method initializes the object’s data attributes.
  • • The method name should start with two underscores and end with two underscores.

Purpose of “self” parameter:

  • • It is required in every method of a class.
  • • This parameter refers to the specific object that the method operates on.
  • • It must be present in a method.
  • • It is automatically assigned to the object that was just created.

Example:

#define the class Emp_class

class Emp_class:

         #defined the init method

         def __init__(self, name, salary):

              #assign name

              self.name = name

              #assign salary

              self...
