We wrote this book to be as accessible as possible and to teach you many different approaches to programming with Python through several scripts. However, to get the most out of them, you need to do the following:

• Have a Linux system set up and configured for testing/debugging scripts
• Understand the created scripts
• Keep in mind what the components of each script are
• Check how the components could be reused or combined in new ways

This book assumes a certain level of Python knowledge to begin your journey; these basic skills will not be covered in this book. These skills include the following:

• How to set up and configure a Linux system
• How to install, access, and configure a specific Python IDE (although several are
  already included in most Linux distributions)
• Some basics about computing and programming (although we will do our best to
  provide a crash course)

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: " To unpack the archives shutil module has unpack_archive() function."

A block of code is set as follows:

 >>> 3 * 'hi' + 'hello'
'hihihihello' 

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

  sudo apt install python3-pip
