When an object is to be generated, classes are utilized as templates, whereas methods are functions that are called or invoked.
A class is a template specification of the method(s) and variable(s) of a certain sort of object in object-oriented programming. As a result, an object is a particular instance of a class; instead of variables, it holds real values. One of the fundamental concepts of object-oriented programming is the class.
A class outlines the information included in the objects that are a part of it, including the actions and a collection of data fields known as instance variables (called methods). An object is an element (or instance) of a class, and objects exhibit the behaviors of the classes in which they belong.
We use the self keyword to declare the attribute purchase price (type int), initializing the value to 0.
Therefore, the purchase price attribute declaration is as follows:
self.purchase price equals zero
We just need to invoke the model year and purchase price variables to define the print info() function.
The print info() function is therefore defined as follows:
def print_info(self):
print("Car's information:")
print(" Model year:", self.model_year)
print("Purchase price:", self.purchase_price)
