Selecting a Programming Language Version

Because I have worked with so many programming languages and reported on them in my blog, I get a lot of e-mails from people who wish to know which language they should use. It’s a hard question because I don’t really have inside information about the project, their skills, their organization, or the resources at their disposal. Usually I provide some helpful guidelines and hope that the sender has enough information to make a good selection. Of course, I’ve also discussed the benefits of various programming languages in this blog and direct people here as well. The next question people ask is which version of the language to use.

Choosing the right programming language version is important because a mistake could actually cause a project to fail. I was asked the question often enough that I decided to write an article recently entitled, How to Choose the Right Programming Language Version for Your Needs. This article helps you understand the various issues surrounding programming language version selection. As with choosing a programming language, I can’t actually tell you which version to choose and for the same reasons I can’t select a language for you. At issue are things like your own personal preferences. In many cases, the language version you choose depends as much on how you feel about a specific version as what the version has to offer you as a developer.

An interesting outcome of programming language selection requirements is that I have one book, Beginning Programming with Python For Dummies that uses Python 3.3 and another book, Python for Data Science for Dummies that uses Python 2.7. Of course, I’ve had books that cover two different versions of a language before, so there is nothing too odd about the version differences until you consider the fact that Python for Data Science for Dummies is the newer of the two books. The reasons for my selections appear in Where is Python 3?. The point is that even book authors need to made version choices at times and they’re almost never easy.

Precisely how do you choose language versions in your organization? Do these criterion differ from techniques you use for you own choices (if so how)? Let me know your thoughts on selecting a programming language version at John@JohnMuellerBooks.com.
