Bonjour et bon début d'année 2019,
J'ai voulu installer pyzo pour programmer en python et j'ai procédé ainsi :
- tout d'abord en suivant les instructions de la documentation de la partie C du document de ce site :
http://maths.spip.ac-rouen.fr/IMG/pdf/pyzo-linux.pdf. Message d'erreur lors de l'installation de matplotlib ...
- puis j'ai téléchargé pyzo (Pyzo for linux) à partir de leur site :
https://pyzo.org/start.html. J'ai testé, ça fonctionne sauf quand il s'agit d'utiliser matplotlib. Ci-joint le programme puis les messages d'erreurs.
Merci pour vos conseils et idées !
import random as rnd
import matplotlib.pyplot as plt
L=[rnd.randint(1,5) for i in range(10)]
plt.hist(L,5)
plt.show()
Python 3.5.2 (default, Nov 12 2018, 13:43:14) on linux (64 bits).
