What's New in Python 2.5

Filed under
Software

It's hard to believe Python is more than 15 years old already. While that may seem old for a programming language, in the case of Python it means the language is mature. In spite of its age, the newest versions of Python are powerful, providing everything you would expect from a modern programming language. This article provides a rundown of the new and important features of Python 2.5.

I assume that you're familiar with Python and aren't looking for an introductory tutorial, although in some cases I do introduce some of the material, such as generators.

Changes and Enhancements to the Language Itself

Python 2.5 includes many useful improvements to the language. None of the changes are huge; nor do they require changes to your existing 2.4 code.

Conditional Expressions

Other languages, particularly C and C++, have for years allowed conditional expressions, which are expressions that include an if statement. The idea is simple: You have a variable, and you want to set the variable to one value if some condition is true; otherwise, you want to set the variable to another variable.

Certainly, you could always do this in Python using a block if statement like so:

Open source key to preserving human history, argues Vatican

Ammenti explained that, in order for the manuscripts to be readable, the Vatican Library opted for open source tools that do not require proprietary platforms, such as Microsoft Office, to be read.

Open Source Router Connects US, Australia

The ONOS Project and partners said Wednesday they have demonstrated the real-world practicality of using a router with open source software to connect networks in Australia and the US. The test validates the vision of SDN, open source for carriers, as well as ON.Lab's ONOS network operating system, according to one of its coordinators. "SDN is about disaggregation of closed, proprietary boxes and separating of forwarding planes, control planes and applications," says Guru Parulkar, executive director and board member of ON.Lab , which coordinates ONOS development. The communications test between Australia and the US achieved just that, he says.
