I am learning also. I came up with this;
#!/usr/bin/python
import tarfile
tFile = tarfile.open("/home/david/zip_files/zip.tar.gz", "r")
for f in tFile.getnames():
    print f
    tFile.close()
#fname = "out.txt"
#fobj = open(fname, 'w')
#for line in f:
#    fobj.write(line + '/n')
#tFile.close()
#fobj.close()

My problem is I can not figure out how to write to the file with new
lines, as you can see my attempts at the bottom. This works fine in Linux;
./py_list_zip.py >> out.txt

but I want to learn how to do it within python, plus to understand.

any hints :)

thanks
