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.
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.
