[Tutor] Problem on filtering data

[jarod_v6 at libero.it]

Dear All;
I have a very silly problem.




with open("Dati_differenzialigistvsminigist_solodiff.csv") as p:
    for i in p:
        lines = i.strip("\n").split("\t")
        if lines[8] != "NA":
            if lines[8] :
                print lines[8]

Why I continue to obtain "" empity line?
