    Why use Object Oriented Programming?
            Code will be more readable and organized
            There is less duplicate code, i.e. a more efficient program
            Makes it easier to write larger programs

    What is Object Oriented Programming?
            Atype of programming which uses object
            These objects can be everything
            What is an object?
                    Astructure that contains data
                    Data from this structure can be manipulated
                    Wecan request the data from this structure

    Syntax structure of Object Oriented Programming
             Constructing a class
  1  class YourClass:
  2      def          i n i t     ( s e l f ) :

             Two key things to note
                     class
                     def __init__(self) (constructor)
