Most of mine have to do with developer productovity and I didn’t find until Python 3.5.
– @, the matmul operator
– fstrings (f”{foo}”)
– parameter typing (foo: int = 0) which has exciting work with Cython
– other async features. I forget what library it was (tensorflow?) but for Python 3 it had better async support
* API-wise keyword-only parameters are absolutely fantastic, even (especially!) for non-default params.
* Extended unpacking, and the ability to unpack in collection literals, make the language much more "expressive" (in the sense there are more cases where you can make do with just expressions) which is very convenient.
Even if you like "print" as a function, is it really so important to wipe out the huge inventory of working Python 2 code and stall Python development for a decade? Python 3 is a tragedy.
That is asinine bullshit and you should be ashamed.
> stall Python development for a decade?
The development of Python never stalled, it barely even slowed.
Thanks for the language, but the only thing I'm ashamed of is Python's lost opportunities. How many thousands or perhaps millions of hours of developer time was spent on compatibility or maintaining two versions? What if that energy was directed on the improving the language instead. There's no question that it would be further along than it is now.
