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

Debuggers tools

There are many debugging tools supported in Python:

  • winpdb
  • pydev
  • pydb
  • pdb
  • gdb
  • pyDebug

In this section, we are going to learn about pdb Python debugger. pdb module is a part of Python's standard library and is always available to use.

The pdb debugger

The pdb module is used to debug Python programs. Python programs use pdb interactive source code debugger to debug the programs. pdb sets breakpoints and inspects the stack frames, and lists the source code.

Now we will learn about how we can use the pdb debugger. There are three ways to use this debugger:

  • Within an interpreter
  • From a command line
  • Within a Python script

We are going to create a pdb_example.py script and add the following content in that...
