Re: [Python-ideas] A more readable way to nest functions

Hi, This would break apart as soon as one of left functions takes more than one parameter. Best regards, João Santos On Fri, 27 Jan 2017, 22:08 Brent Brinkley, <brentbrink...@gmail.com> wrote: > HI Everyone, > > I’m relatively new to the world of python but in my short time her

Re: [Python-ideas] Inline assignments using "given" clauses

+1 to this reasoning. One of the main reason python is popular is because code is easy to read, while ":=" would clearly not be as readable as "given". For me the difference between "given" and ":=" is the same as between python and C for loops. On Fri, 11 May 2018 at 09:06 Greg Ewing

Re: [Python-ideas] Inline assignments using "given" clauses

Optimizing syntax for space makes sense for "mathematical" notation since it's commonly written by hand, but putting space above readability in a programming language design feels like a skewmorphism. On Fri, 11 May 2018 at 11:41 Jacco van Dorp wrote: > I dont really like

How do you read something like " while (cmd := get_command()).token != CMD_QUIT:" in plain english? On Fri, 11 May 2018 at 12:15 Jacco van Dorp <j.van.d...@deonet.nl> wrote: > 2018-05-11 11:56 GMT+02:00 João Santos <j...@jsantos.eu>: > > Optimizing syntax for spac

Hi, You can use uvloop <https://github.com/MagicStack/uvloop>, for example, without using asyncio: import uvloop loop = uvloop.new_event_loop() loop.run_forever() Best regards, João Santos On Fri, 25 May 2018 at 02:42, Ken Hilton <kenlhil...@gmail.com> wrote: > On Tue May 22

Re: [Python-ideas] Revisiting Immutable Mappings

One important difference between MappingProxyType and a "proper" frozendict, as analog to frozenset, is that MappingProxyType doesn't have any method to return mutated versions of itself. On Thu, 11 Oct 2018 at 01:24, Steven D'Aprano wrote: > Hi Philiip, and welcome, > > On Wed, Oct 10, 2018 at

Re: [Python-ideas] Retire or reword the "Beautiful is better than ugly" Zen clause

One important difference between master/slave and beautiful/ugly is that the first pair are concrete concepts that typically applies to people, and the second are abstract concepts that always applied also to objects and abstract concepts. On Thu, 13 Sep 2018 at 13:16, Antoine Pitrou wrote:

[Python-ideas] Re: Void type

You can easily achieve this with something like Void = object() def func(param=Void):   if param is Void:     param = "default" or in the wrapper: Void = object() def wrapper(param=Void, **kwargs):   if param is not Void:     kwargs["param"] = param   return func(**kwargs) With some
