* Language itself is nicer and generally more consistent than py2; caveat: also more complex
* Ecosystem is now fragmented and discombobulated
* Byte strings or whatever are more annoying than in any other programming language I've encountered, hard to say whether this is an improvement or regression compared to Python 2. I get more runtime errors, for sure.
* Breaks a lot of old, useful snippets and packages; they are no longer relevant, but you only find out they are broken when you try to run or import them
Who ever it is downvoting this - it's the first sentence of the linked article. I'm reposting it here to show the irony, given that Python 3 turns out to have been the foundation for making Python 3 one of the worlds most popular programming languages, experiencing massive3 growth.
In 2014 it sure felt the way the author portrayed it. It's better now.
Python 3 was, probably, worth it. But not by a lot.
Please, please, let there be no giant, break-the-world, python4.
