+\section{Pourquoi je n'aime pas Python}
+
+Depuis des lustres, autour de moi, je vois de plus en plus de
+gens faire du code en Python,
+certains même font de choses très avancées.
+Et beaucoup de ces gens essayent de me convaincre que c'est
+un langage vraiment trop bien, trop moderne, trop dans la
+\textit{vibe} du devops, battery included, toussa.
+Quelques uns d'entre eux vont même jusqu'à me parler d'un
+certain \textbf{canard} qui faciliterait bien la vie
+des preogrammeurs.
+
+Je ne suis pas convaincu.
+
+
