The issue is now solved I did:

for x in mylist:
    try:
        sku.append(x[4])
    except IndexError:
        pass

Thank you for your help

Optionally:

for x in mylist:
    if len(x) >= 4:
        sku.append(x[4])

But do you really need to save the whole file in a list first?
You could simply do:

for record in csvreader:
  if len(record) >= 4:
      sku.append(record[4])

Or even:

sku = [record[4] for record in csvreader if len(record) >= 4]

Thanks Neil,

I'm still testing it - just trying to clean the things out and be sure
that I can do all of the stuff :)

I will create a list only of the products I have in the DB and will
compare them for prices stock etc... so the list will be smaller :)

Thanks again

Anatoli
