List out of range : I tried to look at the file but conot find where the error lied

I tried this script with my file which contains approx 16 columns and 5243 lines ,

the first column are respectively the key (just integers 1 to 5243) and the second column is the values which are sentences (the sentences can be very long up to paragraph )

When i tried with small file it works beut with the true file , it is not working.

Not an solution but a tip for finding the error:

Try changing this part:

# extraction colonne verbatim
d = {}
with open(sys.argv[1], 'r', encoding='cp1252',) as csv_file:
    csv_file.readline()
    for line in csv_file:
        token = line.split(';')
        d[token[0]] = token[1]

To this:

# extraction colonne verbatim
d = {}
with open(sys.argv[1], 'r', encoding='cp1252',) as csv_file:
    csv_file.readline()
    for line in csv_file:
        token = line.split(';')
        try:
            d[token[0]] = token[1]
        except:
            print(line)

This should give you the wrong token line and you can check it for erros
