this is huge for long collections of the same data type

yep, In those time of qtile 0.11, it used python 3.4 I think

if linked against cpython it doesn’t make a difference

Jamerive 2022-09-29 21:26:37
smol_mazunki 2022-09-29 21:25:44
it basically assumes types won’t change, and fails if it happened, running it twice

yeah, python improved compared to JS. That Is a feature that JS lack and TS came to offer!XDD

smol_mazunki 2022-09-29 21:26:37
it’s just linter hints

python3.11 allows dynamic types just as before

smol_mazunki 2022-09-29 21:27:27
typescript is statically typed

I don-t know. THe thing I know is that qtile was slow and resource consuming and now is fast and resource lightweigh

smol_mazunki 2022-09-29 21:27:50
it probably uses cython now
smol_mazunki 2022-09-29 21:28:25
which is statically typed python-like code extensions which can be imported without effort
smol_mazunki 2022-09-29 21:28:47
essentially it adds static types to the language, bypassing the type checking

and using static types takes out a huge load in processing and memory use, right?

static typing means the types of a variable can’t and won’t change

smol_mazunki 2022-09-29 21:30:47
this is beneficial since you don’t need to check the type at runtime

“you” = the interpreter

welcome to python

Jamerive 2022-09-29 21:32:34
smol_mazunki 2022-09-29 21:31:51
welcome to python

or JS and Interpreted language with dinamic types? SO that is why that kind of languages is slow_

smol_mazunki 2022-09-29 21:32:47
for i in range(1000):
print(i)

there’s gonna be 1000 type checks here

Jamerive 2022-09-29 21:32:54
how do you declare static types on python?
smol_mazunki 2022-09-29 21:33:17
cdef int64 i = 0
for i in range(1000):
print(i)
smol_mazunki 2022-09-29 21:33:38
smol_mazunki 2022-09-29 21:33:17
cdef int64 i = 0
for i in range(1000):
print(i)

there’s no type checking here except on the first round. this is only available in cython

do you need to recall cython library or something like that or it is embebed in pythin interpreter?

you need to import this from a normal python instance

like import cython?

smol_mazunki 2022-09-29 21:34:54
Jamerive 2022-09-29 21:34:36
like import cython?

import my_cython_code

smol_mazunki 2022-09-29 21:35:36
you compile it with cython my_cython_code.pyx
Jamerive 2022-09-29 21:35:42
smol_mazunki 2022-09-29 21:34:54
import my_cython_code

but what is cython exactly? a new kind of language?

smol_mazunki 2022-09-29 21:36:34
there’s some other ways to do it too, but eh

it’s the official way of creating c extensions

Pythonizing Imgui (feat. Cython) and contributing to open source. – YouTube
Dear ImGui is a GUI library for C++ that has Python bindings. Let’s see how to use these Python bindings, and then go through the process of adding a more Pythonic interface to the library by added context manager “with” statement support.

Note: the PR in this video has been ACCEPTED! Coming to a release near you soon!
