Re: Code ?

J'avais corrigé la version GUI, mais j'avais oublié de reporter la correction dans la version CLI. Comme la simulation prend pas mal de temps avec les paramètres par défaut, j'ai rajouté l'affichage de la progression.

Au final, ça donne :

#!/usr/bin/env python3
from random import randint
from statistics import mean, median, pstdev
import time
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 customer, seller
people = [AMOUNT_START] * NB_PEOPLE
timestamp = time.time_ns()
for _ in range(0, NB_LOOP):
 # select two random people
 while True:
 a = randint(0, NB_PEOPLE - 1)
 b = randint(0, NB_PEOPLE - 1)
 if a != b:
 break
 base = min(people[a], people[b])
 people[a], people[b] = pays(people[a], people[b], base)
 if time.time_ns() - timestamp > 1500000000:
 print(f"{round(100*_/NB_LOOP)}%", end='\r')
 timestamp = time.time_ns()
print(f"{round(100*_/NB_LOOP)}%", end='\r')
# 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)}")
