Software Update: Python 3.1

The developers of Python have finally released version 3.1 after one alpha, one beta and two release candidates. Python is an object-oriented programming language that can be used to develop simple to complex platform-independent applications. The 3.x series is no longer backwards compatible with the previous release branches, as the Python developers have stripped the language of old code and some design flaws present. An overview of the differences between 3.1 and 3.0 is on this page to read. The corresponding list of changes looks like this:
