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 14 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.
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.
