Overview of this book

This book will illustrate how and why you should learn Python to strengthen your analysis skills and efficiency as you creatively solve real-world problems through instruction-based tutorials. The tutorials use an interactive design, giving you experience of the development process so you gain a better understanding of what it means to be a forensic developer. Each chapter walks you through a forensic artifact and one or more methods to analyze the evidence. It also provides reasons why one method may be advantageous over another. We cover common digital forensics and incident response scenarios, with scripts that can be used to tackle case work in the field. Using built-in and community-sourced libraries, you will improve your problem solving skills with the addition of the Python scripting language. In addition, we provide resources for further exploration of each script so you can understand what further purposes Python can serve. With this knowledge, you can rapidly develop and deploy solutions to identify critical information and fine-tune your skill set as an examiner.

Index

IndexError

Both IndexErrors and KeyErrors are subclasses to the more general LookupError. IndexError is commonly encountered when working with lists. This error occurs when the program is attempting to access a position that is not indexed by the object. For example, attempting to access the fifth index of a list with three elements will fail.

Recreating the error and going step by step through the faulty function, either by debugging with an IDE or manually in the interactive prompt, can help give a better understanding of where the error is coming from and how to fix it. See the following code:

>>> small_list = ['a', 'b', 'c', 'd']
>>> print small_list[4]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
IndexError: list index out of range
# Check the max index value 
>>> print len(small_list) - 1
3

IndexErrors are generally easily solved; simply check the number of indices in...
