Mastering Python Scripting for System Administrators

By: Ganesh Sanjiv Naik

Overview of this book

Python has evolved over time and extended its features in relation to every possible IT operation. Python is simple to learn, yet has powerful libraries that can be used to build powerful Python scripts for solving real-world problems and automating administrators' routine activities. The objective of this book is to walk through a series of projects that will teach readers Python scripting with each project. This book will initially cover Python installation and quickly revise basic to advanced programming fundamentals. The book will then focus on the development process as a whole, from setup to planning to building different tools. It will include IT administrators' routine activities (text processing, regular expressions, file archiving, and encryption), network administration (socket programming, email handling, the remote controlling of devices using telnet/ssh, and protocols such as SNMP/DHCP), building graphical user interface, working with websites (Apache log file processing, SOAP and REST APIs communication, and web scraping), and database administration (MySQL and similar database data administration, data analytics, and reporting). By the end of this book, you will be able to use the latest features of Python and be able to build powerful tools that will solve challenging, real-world tasks

Chapter 6, File Archiving, Encrypting, and Decrypting

  1. Yes, using the pyminizip library of Python.
  2. Context managers are a way of allocating and releasing some sort of the resource exactly where you need it. The simplest example is file access:
with open ("foo", 'w+') as foo:
is similar to
foo = open ("foo", 'w+'):
  1. Pickling in Python refers to the process of serializing objects into binary streams, while unpickling is the inverse of that.
  2. Function with no argument and no return value
    Function with no argument and with return value
    Function with argument and no return value
