Python classes / courses - what version do we train on?

Usually, the release number of a programming language that's used on a 'first level' course doesn't make a big difference as the changes tend to be quite minor - after all, languages cannot change much for who would develop e piece of code using a syntax that was likely to go out of date? But that's not the case between Python 2 and Python 3, where there were / are distinct changes. For our courses, we're currently 'in transit'

As part of the introduction at the start of the course, I explain a little about the releases and listen to where the delegates are in the changeover. I then present the course as appropriate. Examples in Python 2 and Python 3 will both be available, and delegates will have the choice of which to use during practicals.

Why have we not switched every course to the latest version?

Changes are NOT so large that we need to run two courses.

There is a lot of existing Python 2 code to be maintained, so lots of people still need to know about that

It is recommended that you carry on coding in Python 2.6 until all your target systems have been upgraded, using the 2 to 3 converter each time you're installing on Python 3. So there's a lot of coding still going on using 2.6 syntax!

Our next Python courses:
