Python is an OOP (Object Oriented Programming) Language, so, almost everything that is used inside Python, is an object. Now, the Python class is best described as the Object creator or some form of the template to create objects in Python. Now, an Instance Attribute is labeled as a variable that fits only to one object. And this variable is accessible through this object and is only defined inside the constructor. If you are searching for a good course in Python, I recommend you check out the Python training course from Intellipaat. Also, have a look at the Python Interview questions video and get started.
