Last updated on Aug 5, 202016109Python is a super-popular programming language particularly suited for developing GUIs and web applications. It is also an extremely popular choice for application development because it offers dynamic typing and binding options. In this article, we will be learning about objects and classes in Python.
In this article, we’ll be exploring the following topics:
The class can be defined as a collection of objects that define the common attributes and behaviors of all the objects. To sum up, it can be called a blueprint of similar objects.
For better understanding, let’s go through an example. In this case, we are considering a Person as a class. Now, if a person is a class, every person has certain features, such as name, gender, and age. Every person has certain behaviors, they can talk, walk, run, or vote.
Class is defined under a “class” keyword.
Example:

Just like everything in the real world is an object, so is the case with the OOPS programming paradigm.
The object is an entity that has state and behavior. It is an instance of a class that can access the data.
Example:
Fig: Defining an object
The _init_ method is run as soon as an object of a class is created. This method is useful for passing initial value to your objects.

“Self” represents the instance of the class. It binds the attributes to the given arguments.
Fig: Creating class and objects
Here, emp1 and emp2 are objects of the class employee.
You can modify object properties in the following manner:

In the example above, we mentioned the attribute that we wanted to change by specifying the object and its properties.
You can delete the object property by using the ‘del’ keyword.
Fig: Deleting object properties
As you can see, the attribute has been deleted, and you get an error message when you try to print the ‘age’ attribute.
