Overview of this book

The Python 3 Standard Library is a vast array of modules that you can use for developing various kinds of applications. It contains an exhaustive list of libraries, and this book will help you choose the best one to address specific programming problems in Python. The Modern Python Standard Library Cookbook begins with recipes on containers and data structures and guides you in performing effective text management in Python. You will find Python recipes for command-line operations, networking, filesystems and directories, and concurrent execution. You will learn about Python security essentials in Python and get to grips with various development tools for debugging, benchmarking, inspection, error reporting, and tracing. The book includes recipes to help you create graphical user interfaces for your application. You will learn to work with multimedia components and perform mathematical operations on date and time. The recipes will also show you how to deploy different searching and sorting algorithms on your data. By the end of the book, you will have acquired the skills needed to write clean code in Python and develop applications that meet your needs.

Logging to Syslog


Unix-like systems usually provide a way to gather logging messages through the syslog protocol, which allows us to separate the system storing the logs from the one generating them.

Especially in the context of applications distributed across multiple servers, this is very convenient; you certainly don't want to log into 20 different servers to gather all the logs of your Python application because it was running on multiple nodes. Especially for web applications, this is very common nowadays with cloud providers, so it's very convenient to be able to gather all the Python logs in a single place.

That's exactly what using syslog allows us to do; we will see how to send the log messages to the daemon running on our system, but it's possible to send them to any system.

Getting ready

While this recipe doesn't need a syslog daemon to work, you will need one to check that it's properly working or the messages won't be readable. In the case of Linux or macOS systems, this is usually...
