☑ What’s New in Python 3.3 - New Features

The fourth Python 3.x release brought another slew of great new features. So many, in fact, that I’ve split this release into two articles, of which this is the first. Highlights in this part include yield from expressions, mocking support in unittest and virtualenv suppport in the standard library.

This is the 5th of the 31 articles that currently make up the “Python 3 Releases” series, the first of which was What’s New in Python 3.0.

☑ What’s New in Python 3.3 - More New Features

The second of my two articles covering features added in Python 3.3, this one talks about a large number of changes to the standard library, especially in network and OS modules. I also discuss implicit namespace packages, which are a bit niche but can be useful for maintaining large families of packages.

Another installment in my look at all the new features added to Python in each 3.x release, this one covering 3.2.

If you’re puzzled why I’m looking at releases that are years old, check out the first post in the series.

☑ What’s New in Python 3.0

I was slow to make the transition from Python 2 to 3 in the first place, and I never felt like I kept up properly with the new features. So I’m going to aim to do a series of articles looking at a different Python version in each and go through the new features added and catch myself up properly. This one addresses features added in Python 3.0 beyond those already in 2.6, including Unicode by default, type annotations, and exception chaining.

This is the 1st of the 31 articles that currently make up the “Python 3 Releases” series.
