Re: Code ?

Il me semble que c'est celui de ce commentaire : https://linuxfr.org/users/fdf/journaux/un-article-de-pour-la-science-m-ayant-amener-a-coder-pour-une-petite-verification-perso#comment-1860111, mis à part le problème de virgule signalé au commentaire qui suit.

Voici la version corrigée :

#!/usr/bin/env python3
from random import randint
from statistics import mean, median, pstdev
NB_PEOPLE = 500
AMOUNT_START = 2000
NB_LOOP = 5000000
RATE = 0.2
DRATE = 0.05
def pays(customer, seller, base):
 # no advantage for the poorest as no poorest
 if seller == customer:
 customer -= base * RATE
 seller += base * RATE
 # poorest receive the money so add DRATE in the transfer
 elif seller > customer:
 customer -= base * (RATE + DRATE)
 seller += base * (RATE + DRATE)
 # poorest pay the money so deduct DRATE in the transfer
 else:
 customer -= base * (RATE - DRATE)
 seller += base * (RATE - DRATE)
 return seller, customer
people = [AMOUNT_START] * NB_PEOPLE
for _ in range(0, NB_LOOP):
 # select two random people
 a = randint(0, NB_PEOPLE - 1)
 b = randint(0, NB_PEOPLE - 1)
 base = min(people[a], people[b])
 people[a], people[b] = pays(people[a], people[b], base)
# final, show the results
people = sorted([int(p) for p in people])
print(f"Last tranfert base: {base}.")
print(f"people: {', '.join(str(p) for p in people)}")
print(f"avg: {mean(people)} | median: {median(people)} | pstdev: {pstdev(people)}")

On peut la tester ici : https://replit.com/@AtlasTK/LFR124926-cli-python (ça prend du temps avant que le résultat ne s'affiche).

Et la version avec une GUI, pour pouvoir modifier les paramètres sans avoir à modifier le code source : https://replit.com/@AtlasTK/LFR124926-python.
