Description

Experienced professionals in every field face several instances of disorganization, poor readability, and testability due to unstructured code. With updated code and revised content aligned to the new features of Python 3.9, this second edition of Clean Code in Python will provide you with all the tools you need to overcome these obstacles and manage your projects successfully. The book begins by describing the basic elements of writing clean code and how it plays a key role in Python programming. You will learn about writing efficient and readable code using the Python standard library and best practices for software design. The book discusses object-oriented programming in Python and shows you how to use objects with descriptors and generators. It will also show you the design principles of software testing and how to resolve problems by implementing software design patterns in your code. In the concluding chapter, we break down a monolithic application into a microservices-based one starting from the code as the basis for a solid platform. By the end of this clean code book, you will be proficient in applying industry-approved coding practices to design clean, sustainable, and readable real-world Python code.

What happens if an Early Access Course is cancelled?

Projects are rarely cancelled, but sometimes it's unavoidable. If an Early Access course is cancelled or excessively delayed, you can exchange your purchase for another course. For further details, please contact us here.

Where can I send feedback about an Early Access title?

If you have any feedback about the product you're reading, or Early Access in general, then please fill out a contact form here and we'll make sure the feedback gets to the right team.

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.

How is Early Access delivered?

Early Access is currently only available as a PDF or through our online reader. As we make changes or add new chapters, the files in your Packt account will be updated so you can download them again or view them online immediately.

How do I buy Early Access content?

Early Access is a way of us getting our content to you quicker, but the method of buying the Early Access course is still the same. Just find the course you want to buy, go through the check-out steps, and you’ll get a confirmation email from us with information and a link to the relevant Early Access courses.

I'd describe myself as a proficient Python programmer but certainly no expert. I primarily use C/C++ but I've used Python for scripting/algorithms before. Fortunately, this book does a good job of teaching concepts in Python for both new and old users, as well as strong code design for any language.The book starts with a general introduction to good coding practices, then goes over the main features of Python before diving into how these coding practices apply to Python. The book shows lots of clear code examples and visualizations throughout its chapters. I think it does a really great job in getting the reader to think critically about code design, both in the abstract and in concrete implementation with Python.I was introduced to a lot of different terminology and features of Python; I intend to use the book both as a reference and as a launchpad for further self-learning. Definitely recommend if you want to strengthen your Python and code design skills!

I enjoyed this book as this is the sort of information you can only get from an experienced developer. Codecademy cannot teach you these principles. Although I’m a beginner programmer, I was still able to pick up a good amount of clean code techniques from this book (though the books seems to appeal to the intermediate level).

Full disclosure: I got a review copy of this for free.This is a great book for Python programmers who're looking at improving their skills. If you're looking at learning Python, this isn't for you. If you're a intermediate programmer looking to improve your code structing tools, this is a fantastic resource.The book starts with code formatting, meaning of clean code and generous references to PEP and why code formatting, doc strings and style guides are helpful - which is usually not dived into (usually most of them are like - do this, trust us). Also appreciated is a section on type consistency checking with mypy and setting up auto type checks with examples using Makefiles.Along the way, the book focuses on making your code more Pythonic with healthy references to slices, context managers, custom iterable objects, dunder methods , generators, yields and async code.Also notable is an entire chapter dedicated to design principles, unit testing, mocks and some examples on how to start testing with unittest and pytest frameworks. The book ends with couple of chapters dedicated to common design patterns and architecture and you're likely to refer to these chapters quite a lot of times as you implement the techniques in your programs.Overall a great book

Disclaimer: Packt sent me a copy of this book for the purposes of review. I was not paid for this review, nor have they asked me what to say.This is a great book for inexperienced developers looking to get into Python the right way. The author is knowledgable and introduces concepts in a very easy to understand manner. The book is definitely dense, however! I would recommend taking a first pass at this book, but leaving to on the desk as a reference text as you continue to learn.One of the things I really like about this book is that the author really focuses on teaching readers to write Python the way it was meant to be written. "Pythonic" code is one of those things that you need to see to understand what it is, but this book definitely gives a great demonstration of pythonic code. Part of writing Pythonic code is understanding context - and Mariano does a solid job of ensuring readers that there are contexts where practicality is more important than purity.Overall - whether you're new to programming, or you're already a programmer but looking to get into Python - give this book a go, I don't think you'll be disappointed.
