Rename .txt files to values separated by comma at first line in file?

Question

Following this thread: Rename .txt files to first line in file? I came up with this code:

import os
for filename in os.listdir("."):
   if filename.endswith(".txt"):
        base, ext = os.path.splitext(filename)
   with open(filename, 'r') as infile:
        newname = infile.next().rstrip()
   newname += ext
   os.rename(filename, newname)

This works well, but what I really need is to name the file not after the entire first line, but after string located between commas. The first line has various values separated by commas (csv), and I need to rename the file with the second value, that is, the string of text that appears between the second and third commas.

I have found a csv module, but I don't know if it helps or how to use it. I found that I could import it this way: import unicodecsv as csv to avoid strange character problems.

Any help would be appreciated. Thanks

tanks to @Joran Beasley it is working perfectly well, the code now is:

import os
for filename in os.listdir("."):
   if filename.endswith(".csv"):
        base, ext = os.path.splitext(filename)
   with open(filename, 'r') as infile:
        newname = infile.next().rstrip().split(",")[1]
   newname += ""
   os.rename(filename, newname)
