Expert Python Programming – Fourth Edition

Current Status of Python

Python is amazing. It is amazing because it has managed to stay relevant and keep growing for so many years.

For a very long time, one of the most important virtues of Python was interoperability. Thanks to that feature it didn't matter what operating system you or your customers were using. If the Python interpreter was available for a given operating system, your software written in Python would work there. And, most importantly, your software would always work the same way regardless of that operating system. However, this is now a common trait. Many modern programming languages provide similar interoperability capabilities. Also, with the advent of cloud computing, web-based applications, and reliable virtualization software, it isn't that important to have a programming language that works in many operating systems.

What seems to be increasingly more important for programmers nowadays is productivity. With a constant search for...

Where are we now and where are we going?

Python isn't a young language. Its history starts somewhere in the late 1980s and the official 1.0 release happened in year 1994. We could discuss the whole timeline of major Python releases mentioned here, but we really only need to be concerned about a few dates:

  • October 16, 2000: official release of Python 2.0
  • December 3, 2008: official release of Python 3.0
  • November 9, 2011: announcement of Python 2.8 release un-schedule
  • January 1, 2020: official sunsetting of Python 2

So, at the time of writing, Python 3 is almost half as old as Python itself. It has also been active for longer than Python 2 was when it comes to active development of new language features.

Although Python 3 has been around for quite some time, its adoption was so slow that the initial end of life for Python 2 was postponed by 5 years. It was mostly due to a lot of backward compatibility issues that didn't always allow...

What to do with Python 2

We know that Python 2 is no longer officially supported by language developers. Due to the lack of security patches, it should be considered unsafe. But is it dead yet?

Probably not. Even relatively popular open-source libraries can lose the interest of their authors and contributors over time. It also happens that some better alternatives appear, and there's simply no point in developing the original library anymore. Such libraries are often left unmaintained, so no one could update them for compatibility with Python 3.

One of the important reasons why Python 3 couldn't take off for a long time was the sluggish release processes of many Linux distributions. Distribution maintainers often aren't inclined toward the fast adoption of new language versions, especially if these versions break backward compatibility and require patches of other software. Many Python programmers are Linux users, and if they don't have access to the latest...

Keeping up to date

Technology evolves constantly. People are constantly looking for tools that will allow them to solve their problems more easily than before. Every few months, either a completely new language pops up almost out of nowhere, or one of the well-established languages introduces a completely new syntax feature. This also happens to Python. We will briefly consider a few of the most important recent additions to the Python language in Chapter 3, New Things in Python.

New languages or language features drive the creation of novel libraries and frameworks. These in turn open the way for new programming paradigms and new design patterns. The success of one such pattern or paradigm in one language ecosystem often encourages programmers to adopt them in other languages. That's how new ideas spread from language to language.

We see that happening to Python too. We will be able to see how seemingly different programming languages share similar features or...

Summary

In this chapter, we've discussed the current status of Python and the process of change that is visible throughout the history of that language. We've learned why Python is changing and why it is important to follow that change.

Staying relevant is one of the biggest and most stressful challenges that professional programmers face regardless of the programming language they choose. Due to over 30 years of Python history and the ever-growing Python community, it isn't always clear how to efficiently stay up to date with the changes in the Python ecosystem. That's why we've looked into all the places where you can follow important discussions about Python's future.

What also changes together with the language are development tools that aim to ease and improve the software development processes. In the next chapter, we will continue with the topic of change and take a look at modern development environments. We will learn how to create repeatable...

I have 7+ years of professional experience as a programmer and have been coding in Python since 2019. I love the comprehensiveness of this book and I learned so much not only "how to do X" but "why to do X" --- it gave best practices and I'm not just repeating what the book tagline says. For someone with limited experience working in big companies / teams, the book is very insightful.It is also easy to read; I finished this book in ~2 weeks by setting a goal of reading 35 pages/day. (Some days I read more)My only "complaint" is that there were a bit of typos but they weren't super critical. It was very obvious that they are typos and they're not a lot so it's not super distracting and most importantly, you won't be left "confused."

The media could not be loaded. I have about two years of experience using Python, and I find this book very helpful in moving forward. The first chapter gets everyone off to a great start by sharing ideas about how to stay up-to-date with Python, as the language inevitably changes, and where to find Python community. All of the chapters are important and contain great information. I particularly like Chapter 4 which compares Python to other languages, and emphasizes that just because you might be able to write code as you would in another language, that is not necessarily the "Python way", nor the best way to do it in Python. The chapter identifies places where programmers might try things they really shouldn't. I have combined C/C++ code with Python, and so, I enjoyed reviewing the chapter which covers this topic. I closely read and enjoyed the chapter on Optimizing Code, one way of course is via choosing the best data structure. This helps the programmer learn not just what data structures are available but provides info on how data structures can impact performance. I have not had to profile code, but I think Chapter 12 would be very useful on that. I am very interested in going further and carefully reading the chapters on Interfaces, Patterns, and Modularity, on Testing and QA, as well as Concurrency, and Meta-programming. There is a lot of great material here.

I have written Python code for about 15 years now. Even though many times that hasn't been what I wrote for my day job, it is still my favorite programming language. I didn't think there was much to learn, but then again I started as a Python 2 developer and only switched to Python 3 in the last few years.But this book is great and taught me a bunch of new things. I learned about Poetry, which I never heard of until now, and can't wait to use it on my next project. It also walks you through using Docker for development and explains why you may want to still use Vagrant in some cases even though it is an older technology. It even goes into writing C extensions to give your Python projects a performance boost.You should know some Python before reading this book, as it goes into some concepts in-depth, but I would recommend it to anyone who has been writing Python code for a few months.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
