What programming concept allows for the creation of objects?

The concept that allows for the creation of objects is classes. In object-oriented programming, a class serves as a blueprint for creating objects. It defines the properties and behaviors, known as attributes and methods, that the objects created from the class will have. When you instantiate a class, you create an object, which is an instance of that class. This encapsulation of data and functionality is central to object-oriented design, enabling code reusability, organization, and modularity.

Functions, while they can perform actions and return values, do not inherently create objects; they simply define behavior. Modules and libraries are collections of code that can include functions, classes, and other definitions, but they do not specifically relate to the intrinsic capability to create objects on their own. Thus, classes embody the structure and relationships needed to define objects in programming.
