theme editor problem/issue

Hello everybody ! I’m french and new in this community !

I’m trying to get ready my newspaper theme on my website.
I have to translate some sentences in french like the comments form… so I went to the theme editor in wordpress to change english sentences to french sentences in comments.php file. I give you an example :

$defaults[‘comment_notes_before’] = ”;
$defaults[‘comment_notes_after’] = ”;
$defaults[‘title_reply’] = esc_html__(‘LAISSER UN COMMENTAIRE’, ‘newspaper’);
$defaults[‘label_submit’] = esc_html__(‘Poster le commentaire’, ‘newspaper’);
$defaults[‘cancel_reply_link’] = esc_html__(‘Annuler la réponse’, ‘newspaper’);

I translated every esc_html__ in french, but when I save my changes, there isn’t my translation on my website 🙁

Pleaseee 😀
Thx
