Python coincé dans une boucle While infinie ?

Premier utilisateur de python ici. J'essaie d'utiliser une boucle while pour configurer un type d'outil de recherche pour les cours scolaires. J'obtiendrai les invites pour insérer le sujet et le CatalogNbr ; mais au lieu d'imprimer le nom du cours (par exemple "Introduction à la recherche" du premier bloc) comme j'en ai besoin, il revient immédiatement à demander à nouveau des entrées pour le sujet et le CatalogNbr.

D'après ce que j'ai recherché jusqu'à présent, je dois inclure des instructions break et continue entre les boucles, mais chaque fois que j'essaie d'inclure celles-ci, j'obtiens des erreurs de syntaxe.

Toute aide sur la façon d'accomplir cela sera grandement appréciée
