Writing in a document problem

[IOHANNES]

You can loop direclty over the file object,and range() is not nessesary.
Try to use with open then no need to close file obejct,also using f-sting make it nicer.
Then it can be done like this.

with open('list_fable.txt') as fp,open('list_out.html', 'w') as fp_out:
    for line in fp:
        fp_out.write(f'<title>{line.strip()}</title>\n')

list_out.html:

Output:
<title>Le Dépositaire infidèle</title>
<title>Les Deux Pigeons</title>
<title>Le Singe et le Léopard</title>

very clear thanks
