"Cet exercice est facultatif, il permet de tester votre niveau Python. Les questions traitent au maximum le thème financier, mais ne vous attardez pas sur ces tâches, beaucoup d’entre elles n’ont aucune signification et n’ont pas de sens. Si vous trouvez cela extrêmement difficile, vous n'êtes probablement pas encore prêt pour le reste de ce cours et n'avez pas assez d'expérience en programmation pour continuer. Je vous suggère de prendre un autre cours plus orienté vers les débutants complets, tels que [Formation complète Python](https://www.udemy.com/course/python-datascience/?referralCode=9DB381B321631A0703C2)"
