The basic idea behind OOPs is to combine data and the functions that interact with it into a single entity so that no other parts of the code may touch it. OOP generally organizes your program into reusable units called classes and objects. This makes your code modular, easy to debug, ...
Files within the directory can reference other files within the same directory, or even within subdirectories. But the entire collection of files is presented to other Python code as a single module — as if all the functions and classes were in a single .py file....
