☑ Python 2to3: What’s New in 3.3 - Part 2

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.

This is the 5th of the 15 articles that currently make up the “Python 2to3” series, the first of which was Python 2to3: What’s New in 3.0. This article was preceded by Python 2to3: What’s New in 3.3 - Part 1.

☑ Python 2to3: What’s New in 3.3 - Part 1

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.

☑ Python 2to3: What’s New in 3.2

Another installment in my look at all the new features added to Python in each 3.x release, this one covering 3.2. There’s a lot covered including the argparse module, support for futures, changes to the GIL implementation, SNI support in SSL/TLS, and much more besides. This is my longest article ever by far! If you’re puzzled why I’m looking at releases that are years old, check out the first post in the series.

This is the 3rd of the 15 articles that currently make up the “Python 2to3” series, the first of which was Python 2to3: What’s New in 3.0. This article was preceded by Python 2to3: What’s New in 3.1.

☑ Python 2to3: What’s New in 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 15 articles that currently make up the “Python 2to3” series.
