Python 2.7.9 Update

Beginning Programming with Python For Dummies is based on Python 3.3. However, I know that some of you are using Python 2.x installations instead. My book does discuss some of the differences between the two releases and makes you aware of examples that won’t work. However, if you do decide to use Python 2.x despite the limitations when it comes to the book, I highly recommend you get the Python 2.7.9 update. The update contains a slew of important bug fixes, many of which affect security, which is always an important issue when it comes to applications.

A reader recently sent me an InfoWorld Tech Watch article that highlights the updates in the 2.7.9 release for you. The most important thing to know from a book perspective is that the update doesn’t offer any new features. This means that if an example didn’t work with 2.x in the past, it won’t work with 2.7.9 either.

A number of readers feel that the Python 2.x releases are better and the bug updates simply mean that it remains popular. Because the 3.x release is the preferred release, I chose to focus on it when I wrote the book. Yes, you can use my book with the 2.x release, but I guarantee some examples simply won’t work with it.

Please let me know if you have any other questions about my book, the level of Python support it provides, or whether the Python 2.7.9 release will provide any book-related advantage other than ensuring your system will remain safe at I want to ensure you have the best reading experience possible. However, there isn’t any chance at all that I’ll rewrite book examples to work with 2.x unless there is a significant number of readers who want this feature. Even then, some examples simply won’t work because there is no workaround to make them work (essentially the reason we needed the 3.x update).
