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

Pandas module

In this section, we are going to learn about the pandas module. The pandas module provides fast and flexible data structures that are designed for working with structured and time series data. The pandas module is used for data analysis. The pandas module is built on packages such as NumPY and Matplotlib and gives us a place to do most of our analysis and visualization work in. To use the functionality of this module, you must import it first.

First, install the following packages that we need in our examples by running the following commands:

$ pip3 install pandas
$ pip3 install matplotlib

Here, we are going to look at some examples of using the pandas module. We will learn about two data structures: Series and DataFrames. We are also going to see how we can read the data from a csv file using pandas.
