Python: Object Oriented Programming - 2 . Recap • Object Orientation – merge data and functions (that operate on the ... new object of type Coordinate with initial attributes . Operator Overloading What the operator does, depends on the objects it operates on. For example:

– details associated with object sub-components are enclosed within the logical boundary of the object – user of object only “sees” the public interface of the object, all the internal details are hidden Note - In Python, encapsulation is merely a programming convention. Other languages (e.g., Java) enforce the concept more rigorously.

Every variable in python holds an instance of an object. There are two types of objects in python i.e. Mutable and Immutable objects. Whenever an object is instantiated, it is assigned a unique object id. The type of the object is defined at the runtime and it can’t be changed afterwards.

Object Orientation in Python Python is a dynamically typed language, which means that the type (class) of a variable is only known when the code runs. Duck Typing: No need to know the class of an object if it provides the required methods. “When I see a bird that walks like a duck and swims like a duck and

• Binding a variable in Python means setting a name to hold a reference to some object. • Assignment creates references, not copies • Names in Python do not have an intrinsic type. Objects have types. • Python determines the type of the reference automatically based on the data object assigned to it.
