Chapter 5, Handling Files, Directories, and Data, is where you will learn about using the os module for various activities. You will learn about the data and some methods applied to that data, such as copying, moving, merging, and comparing. You will also learn about the tarfile module and how to use it.
Chapter 6, File Archiving, Encrypting, and Decrypting, delves into file archiving, creating archives, and TAR and ZIP creation. You will also learn about unpacking the .tar and .zip files using applications.
Chapter 7, Text Processing and Regular Expressions, looks at text processing and regular expressions in Python. Python has a very powerful library of things called called regular expressions, which do tasks such as searching and extracting data. You will learn how to use regular expressions with files. You will also learn how to read and write to files.
Chapter 8, Documentation and Reporting, will teach you how to document and report information using Python. You will also learn how to take input using Python scripts and how to print the output. Using Python, you can write scripts for automated information gathering. Writing scripts for receiving emails is easier in Python. You will learn how to format information.
Chapter 9, Working with Various Files, will go into the issue of handling various files, such as PDF files, Excel files, and CSV files. You will learn how to open, edit, and get data from these files using Python.
Chapter 10, Basic Networking – Socket Programming, will first introduce the basics of networking; then you will learn about sockets such as TCP, UDP, and more. You will also learn about how to program sockets to communicate and get information of protocols such as HTTP and FTP.
Chapter 11, Handling Emails Using Python Scripting, explores how to compose and send emails using Python scripts. Sending emails is a very common task in any software program. We can use Python's smtplib module for sending emails in Python programs. In this chapter, you will also learn about the different protocols used for sending emails on different servers.
Chapter 12, Remote Monitoring of Hosts Over Telnet and SSH, shows you how to carry out basic configurations on a server with the SSH protocol. We will begin by using the Telnet module, after which we will implement the same configurations using the preferred method, SSH.
Chapter 13, Building Graphical User Interface, looks at graphical user interface creation with the PyQt module.
Chapter 14, Working with Apache and Other Log Files, explains how to work with Apache log files. You will also learn about log-parsing applications; that is, identifying the particular types of log messages. You will also learn how to parse these files and how to handle multiple files; detecting any exceptions, storing data, and producing reports.
Chapter 15, SOAP and REST API Communication, concerns the basics of SOAP and REST, and the differences between them. You will also get to know the SOAP API and how to use it using different libraries. We will also study the REST API and standard libraries.
