[∇] [Δ] Programmes OLPC traduits en Python 3

Le projet OLPC (One Laptop per Child) a été lancé en 2005 pour développer « un ordinateur portable pour chaque enfant ».

Ce projet a suivi l’évolution des technologies et a permis de créer des logiciels éducatifs libres utilisables sur les portables et les tablettes modernes.

L’essentiel de ces objectifs sont repris par la plateforme Sugarizer.

La plupart des applications OLPC originales avaient été développées en Python 2 et sont disponibles sur le Wiki d’OLPC.

On trouvera ci-dessous une sélection de ces applications traduites en Python 3.

Let's do math!
On Monday I picked 22 apples. On Tuesday I picked 12.
Now I have: 34

My brother says he picked twice as many apples last week.
This means he picked: 68

I have 3 friends to whom I would like to give apples.
One third of my apples is about: 11
Or, more exactly: 11.333333
