Question
Before we can go into how to work with files in Python, it’s important to understand what exactly a file is and how modern operating systems handle some of their aspects.
At its core, a file is a contiguous set of bytes used to store data. This data is organized in a specific format and can be anything as simple as a text file or as complicated as a program executable. In the end, these byte files are then translated into binary 1 and 0 for easier processing by the computer.
