I would recommend using the glob module to grab a list of the files
you want or you can just create your own list. Then use a loop to grab
the lines you want. Something like this:

f = open(textFile)
newFile = open(newFileName, "a")
x = 1
for line in f.readlines():
    if x >=7 and x <=11:
         newFile.write(line + "\n")

You could even put the above inside a loop that loops over the list of
files. Anyway, that's one approach. I'm sure there are many others.
