#Itertools
I need to add #itertools groupby in my classes :)

@pokateo use of python `itertools` to map `shapely` functions onto geometric linear and point objects
#ArtAdventCalendar Day 4.
I started working through the book "Indra's Pearls" by David Mumford, Caroline Series, and David Wright. And by working, I mean implementing the pseudo-code in #python. It's fun when you recognize that a messy triple-nested loop algorithm in the book can be replaced by a single `itertools.product` followed by a `filter` call - which makes one appreciate the ease of coding in Python!
This is a "Theta-Schottky group" fractal inspired by Exercise 4.2 in the book.
Ano passado eu gravei um curso em vídeo de introdução ao desenho com código, usando #Python + #Processing (#py5) para o HomeostasisLab, está disponível *totalmente de graça* em:
https://homeostasislab.org/cursos/info/131
Parece que uma centena de pessoas acessaram esse #cursoGrátis de #ProgramaçãoCriativa, mas eu não tive retorno. Estranhei que deveria ter legendas em inglês mas não as encontrei :((
Adoraria que mais gente visse e que me mandassem comentários (de preferência construtivos). Assisti ontem um trechinho em que eu tento explicar #itertools #combinations #permutations e #ItertoolsProduct e achei que estava bem razoável.

UPDATE: No need to use that cumbersome lambda, it was there because of some previous experiments... I refactored it out:
...
for z, positions in zip(range(-100, 101, 20), cs):
py5.fill((255 + z + i * 20) % 255, 200, 200)
for pos in positions:
element(pos + (z,))
Today I implemented some neat optimizations for my current project at work: the problem I found was that the #rust #itertools library does not ensure minimal allocation size for the partition_result adaptor.
I made a custom implementation of this adaptor that does not allocate itself, but receives preallocated collections for the partitions.
Was a pretty nice experience.
Ano passado eu gravei umas aulas em vídeo para o HomeostasisLab, é de graça, sobre desenhar com #Python e #py5 e um pouquinho de #itertools https://homeostasislab.org/cursos/info/131

Will I get the hang of using #py5 on #JupyterLab ? Trying the py5bot kernel...
