Bonjour Hossein,

Ça me semble bon, quand tu lances ton script le "Hello" est bien affiché.

Par la suite tu lances l'installation d'un module (autopep8) avec pip et l'installation ne fonctionne pas car tu n'as pas les permissions. Dans ce cas je te conseille de lancer ton terminal en tant qu'administrateur pour éviter ces problèmes de permission sur Windows.

Je te conseille également d'utiliser les terminaux que je recommande pour Windows (Git Bash ou Cmder). Comme ça tu auras exactement les mêmes commandes que moi sur un terminal Bash :)
