Le projet Euler est un site très amusant et pédagogique qui propose de résoudre des problèmes mathématiques en écrivant des programmes dans le langage de son choix. J'essaye de venir à bout des plus de 200 exercices proposés en utilisant Python.

Voici la liste des problèmes que j'ai résolus pour le moment. Cette page est dédiée à Monsieur T. et Monsieur L., professeurs qui on tout fait pour me dégoûter des mathématiques au lycée, ainsi qu'à Madame X., conseillère d'orientation qui failli me convaincre que mes mauvaises notes dans cette matière me fermeraient à jamais le métier de programmeur.
