looking for data on csv files

[flit]

Hi!
I am using the csv modules..

when I use the command:

if nome in row[rowcsv]:
            print "\n"
            print row[rowcsv] + "\n  ---->   " + row[11] + "\n"
            print
"################################################################"

there is this case:

1- data on file PUItarr

If the user try to find for puitarr or PUITARR it doesn´t find.

I tried the string.upper and .lower , but there is a a way to look far
all possible combinations?

And yes, i am a newbie..
