Python est un langage de programmation interprété, de haut niveau et à usage général. Contrairement à HTML, CSS et JavaScript, principalement utilisés pour le développement web, Python est polyvalent et peut être utilisé dans divers domaines, notamment le développement logiciel, la science des données et le développement back-end. Dans ce cours, vous explorerez les aspects fondamentaux de Python et, à la fin, vous créerez vos propres fonctions.

Apprenez à utiliser les opérateurs de comparaison et logiques, à manipuler les expressions conditionnelles, et à appliquer les comparaisons d'appartenance et de type. Acquérez une base solide pour écrire des programmes qui réagissent dynamiquement à différentes conditions à l'aide des structures if/else et if/elif/else.
