Bonjour,
Je travaille sur Mac OSX 10.12.3 avec PYZO :
Python 3.5.2 |Anaconda 4.1.1 (x86_64)| (default, Jul 2 2016, 17:52:12) on
darwin (64 bits).
This is the Pyzo interpreter with integrated event loop for PYQT4.
Je n'arrive pas à obtenir le script du programme suivant :
import matplotlib.pyplot as plt
from random import random
from math import sqrt
taille=int(input('Taille des échantillons : '))
p=float(input('Proportion : '))
nb_d_echant=100
def freq_echantillon():
ok=0
for k in range(taille):
if random()<p:
ok+=1
return ok/taille
bi=p-1/sqrt(taille)
bs=p+1/sqrt(taille)
compteur=0
for i in range(nb_d_echant):
couleur='r'
rep=freq_echantillon()
if bi<rep and rep<bs:
compteur+=1
couleur='g'
plt.scatter(i/nb_d_echant,rep,c=couleur)
plt.plot([0,1],[bi,bi])
plt.plot([0,1],[bs,bs])
plt.xlabel(str(100*compteur/nb_d_echant)+' % des échantillons sont entre les
bornes : '+str(round(bi,3))+' et '+str(round(bs,3)))
plt.show()
Voici le message d'erreur :
