When I was replacing peewee with PonyORM, I was evaluating a few options, including moving away from an ORM entirely and simply storing the metadata in indexed tables in memory. This would have also helped to solve a couple of minor annoying design issues (such as improper encapsulation of the actual content state into the application instance), but I ended up not doing this.| beesbuzz.biz
The conflict between subclassing and composition is as old as object-oriented programming. The latest crop of languages like Go or Rust prove that you don’t need subclassing to successfully write code. But what’s a pragmatic approach to subclassing in Python, specifically?| Hynek Schlawack
namedtuple has been around since forever, and over time, its convenience saw it used far outside its originally intended purpose.
