Le but de mon code est de mettre la chaîne de caractères datastr
dans la liste bidimensionnelle matrix
. Cela fonctionne parfaitement dans Code_v1 mais lorsque je mets le même code dans une fonction datastr = datastr.replace("\n", " ")
ne remplace pas le \n
de la même manière que dans Code_v1 (formulaire un " "
à plusieurs " "
s ; comparer Sortie_v1 à Sortie_v2).
Pourquoi est-ce le cas et comment puis-je y remédier ?
J'ai déjà lu de nombreuses autres questions concernant .replace(old, new)
mais ils ont tous écrit string.replace(old, new)
au lieu de string = string.replace(old, new)
.
Merci d'avance pour vos réponses.
P.S. Je ne veux pas utiliser matrix
pour les mathématiques. C'est pourquoi j'utilise une liste à deux dimensions et non pas numpy.matrix
.
P.P.S. Il s'agit de mes premières questions. Si quelqu'un a une suggestion pour améliorer la lisibilité de la question ou toute sorte d'amélioration pour mon codage, s'il vous plaît dites-moi.
