Some people are excited about eventually being able to program in Python 3 everywhere. What I’m looking forward to is being able to program in Python-with-attrs everywhere. It exerts a subtle, but positive, design influence in all the codebases I’ve see it used in.
Or, for those who want more power (an complexity) than the attrs module, there’s macropy and it’s case-classes.
Stackoverflow has introduced a new tech documentation tool that focuses on providing examples, rather then merely sparsely documenting an API. The one on Python string formatting is quite useful.
