What is an Object?

In Python, every piece of data you see or come into contact with is represented by an object. Each of these objects has three components: an identity, a type, and a value. The identity represents the location of the object being held in your memory (and therefore is unchangeable), while its type tells us what types of data and values it can have. The value, meanwhile, can be changed in an object, but only if it is set as a mutable type; if it is set as immutable, then it may not change.
 
Integers, strings, lists, and so forth are all nothing more than objects. Now, it is all well and good to have all of these floating around within your program, but wouldn ’ t it make more sense to have the ones that work closely together in one spot? That is where classes come in. A class allows you to define and encapsulate a group of objects into one convenient space.
