On the other hand, Python is not just another scripting language; it is a complete object-oriented software development environment that is built for rapid prototyping. In addition, Python is free, open source, cross platform and provides a much easier on-ramp to learn by novice developers and examiners with no previous programming or computer science background. In addition, the availability of free online resources, tutorials, and examples. Also, hundreds of books are available—from introductory level to quite advanced topics.

This code section represents a class, specifically the FileExaminer class. This class, once instantiated, is no different than using a string in Python as everything is a class. Classes have attributes and methods relating to the object that it becomes. In this case, the object encompasses a single file and performs a set of operations to examine the contents of the file. The class can be extended (this will be done later in the book) to perform even deeper analysis of files. To keep things simple, when the object is first activated, it automatically extracts some details about the file that it encompasses.
