Python for Secret Agents - Volume II - Second Edition

By: Steven F. Lott

Overview of this book

Python is easy to learn and extensible programming language that allows any manner of secret agent to work with a variety of data. Agents from beginners to seasoned veterans will benefit from Python's simplicity and sophistication. The standard library provides numerous packages that move beyond simple beginner missions. The Python ecosystem of related packages and libraries supports deep information processing. This book will guide you through the process of upgrading your Python-based toolset for intelligence gathering, analysis, and communication. You'll explore the ways Python is used to analyze web logs to discover the trails of activities that can be found in web and database servers. We'll also look at how we can use Python to discover details of the social network by looking at the data available from social networking websites. Finally, you'll see how to extract history from PDF files, which opens up new sources of data, and you’ll learn about the ways you can gather data using an Arduino-based sensor device.

Mastering the Arduino programming language


The Arduino programming language is based on C++. In Python, we use indentation to identify the body of an if statement, while statement, a function, or a class. An Arduino sketch will use {} instead of indentation.

While the {} are required syntax, almost all Arduino code that we'll see will be nicely indented as if it was Python.

Similarly, Arduino statements are separated by ; (semicolon). Python statements end at the end of the line, or the end of the matching (), [], or {}. It's challenging—at first—to remember the ; (semicolon). When we try to upload the sketch to our Arduino, the final syntax check will alert us to missing ;(semicolon).

Arduino has two kinds of comments: everything after // is a comment. This is similar to Python's # comment delimiter. Also, Arduino programs can have longer comments which begin with /* and end with */. This will often be used similarly to Python's ''' triple-quote strings. The Arduino /* */ comments can be used...
