An object is anything that you wish to manipulate or change while working through the code. Every time a class object is instantiated, which is when we declare a variable, a new object is initiated from scratch. Class objects can be used over and over again whenever needed.Creating Classes. When we create a class we are essentially creating our own data type. To do this we must first come up with a name for our class and populate it with some methods. class Dog (): def __init__ (self): pass def speak (self): pass. The name of this class is "Dog" and currently it has two methods: init and speak.We can think of classes in Python in a similar way. A class represents a type (clock) and we can create many instances of that type (clocks in the photo above). Object oriented programming (OOP) paradigm is built around the idea of having objects that belong to a particular type. In a sense, the type is what explains us the object.

Suppose a class is a prototype of a building.New style classes were introduced in python 2.2. A new-style class is a class that has a built-in as its base, most commonly object. At a low level, a major difference between old and new classes is their type. Old class instances were all of type instance. New style class instances will return the same thing as x.__class__ for their type.Classes are essentially a template to create your objects. A very basic class would look something like this: We'll explain why you have to include that "self" as a parameter a …

Python includes mechanisms for doing object-oriented programming, where the data and operations on that data are structured together.The class keyword is how you create these structures in Python.Attributes are the data values, and methods are the function-like operations that you can perform on classes.
