• A computer with an internet connection
• Python 2.7.15 or Python 3.7.1
• Optionally, an IDE for Python

In addition to these requirements, you will need to install various third-party modules that we will make use of in our code. We will indicate which modules need to be installed, the correct version, and, often, how to install them.

The code bundle for the book is also hosted on GitHub at https://github.com/PacktPublishing/Learning-Python-for-Forensics-Second-Edition. In case there's an update to the code, it will be updated on the existing GitHub repository.

We also have other code bundles from our rich catalog of books and videos available at https://github.com/PacktPublishing/. Check them out!

We also provide a PDF file that has color images of the screenshots/diagrams used in this book. You can download it here: https://www.packtpub.com/sites/default/files/downloads/9781789341690_ColorImages.pdf.

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "This chapter outlines the basics of Python, from Hello World to core scripting concepts."

A block of code is set as follows:

# open the database
    # read from the database using the sqlite3 library
    #     store in variable called records
    for record in records: 
        # process database records here

Any command-line input or output is written as follows:

>>> type('what am I?')
<class 'str'>

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Select System info from the Administration panel."
