Classes and Objects in Programming

In Python, every type is a class. So int, float, complex, bool, str, list, tuple, set, and dict are all classes.

A class has a name, whereas objects are nameless. Since objects do not have names, they are referred to using their addresses in memory.

When we use the simple statement num = 10, a nameless object of type int is created in memory, and its address is stored in num. Therefore, num refers to or points to the nameless object that contains the value 10.

However, instead of saying that num refers to a nameless int object, it is often said for the sake of convenience that num is an int object.

Let’s look at more programmatic examples of classes and objects:
