Can I download the code files for Early Access titles?

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

How accurate is the publication date?

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.

How will I know when new chapters are ready?

We'll let you know every time there has been an update to a course that you've bought in Early Access. You'll get an email to let you know there has been a new chapter, or a change to a previous chapter. The new chapters are automatically added to your account, so you can also check back there any time you're ready and download or read them online.

I am a Packt subscriber, do I get Early Access?

Yes, all Early Access content is fully available through your subscription. You will need to have a paid for or active trial subscription in order to access all titles.

Metaprogramming is nothing new. It is a programming paradigm or technique we use to create programs that can ingest other programs, treating them like data. This can make for a robust and programming environment. This book covers object-oriented programming (OOP), metaclasses, and provides multiple examples of how to use metaprogramming with Python. Knowledge of the Python programming language is assumed and, familiarity with OOP is helpful. This book scratches the surface of metaprogramming with just the right depth of coverage.

This book is for people who want to take their Python programming skills to the next level. The author makes it abundantly clear that knowledge of Python is absolutely necessary to derive maximum benefit from this book. Writing reusable code makes your code base easily maintainable and this is one of the objectives of this book.This book is divided into 3 parts with the first part covering the basics of Metaprogramming and revisiting the OOPS concepts. This section of the book introduces you to why you need metaprogramming and what are its practical applications followed by an overview of OOP concepts along with examples.The second part is a deep dive into the basic building blocks of Metaprogramming in greater detail. Concepts that are covered in this part include how to define decorators and how to work with metaclasses. The next two chapters cover topics on how to employ introspection and reflection on your code. The last two chapters in this section teach the reader about Generics, typing and templates to enhance your code.The third part is a continuation of the concepts that were covered in the previous 6 chapters and build on that knowledge. It covers more advanced topics in the area of metaprogramming. The reader will get a deeper understanding of the structure of the code through abstract syntax trees and the behaviour through method resolution order. The next chapter will help the reader understand the concept of dynamic objects in Python and the process that can be followed to create any dynamic Python objects. The next two chapters cover the concept of design patterns in Python 3. Chapter 15 consolidates the knowledge gained from all the previous chapters by implementing a case study wherein all the metaprogramming concepts learned so far is implemented. The last chapter is about following the best practices and applying the same to Metaprogramming.Each chapter has a detailed code walk-through for all the examples that will help the reader understand the concept being covered in better detail. It would have been better if, at the end of each chapter, there were a few questions based on the concepts covered in the chapter. This would have really helped the reader consolidate the understanding better.I found the book to be very well written as it takes the user on a journey about Metaprogramming in Python. Kudos to Sulekha Aloorravi for writing such a wonderful book.

Great book written with clear explanation of python Meta programming concepts. The case studies used and the way concepts are covered with perfect code snippets makes the book special.

Dileep Vuppaladhadiam Jan 14, 2023

A must read for advanced python programmers. Written in a manner where anybody can adopt & adapt, with or without programming knowledge. Very carefully and logically illustrated Chapter by Chapter. Very well presented and organized Hands-on exercises to get a feel of Meta-programming. Was looking for something so comprehensive for a very long time. This knowledge can be extrapolated to other programming languages as well. Thanks to the author for sharing this expert approach. Looking forward to see more such contributions from the author.

I read the digital copy of the book. As an experienced programmer I skimmed the basics of OOP sections in the early segment of the book because I already know OOP to a reasonabe depth, that said working through the book improved my upfront thinking about generators, decorators and overall class interaction design.I don’t typically create meta classes or metaprogramming much on a day to day basis, I am not a framework author. As such the book challenged me to think in alternate ways, gave me more than a handful of aha moments and made me want to go back and rewrite code I was previously happy with. An interesting read but definitely not for beginners. I enjoyed this title and would give it four stars. Mastering the skills here will up your game quite a bit, add elegance to your designs and make you a better programmer in the end. Terse stuff in places but enjoyable.
