How can I read from line 24 and do further looking for "E".

Thanks,



As I said in my earlier message, this was untested.  It gave you the 
building blocks, but was not correct.

In particular, that if-test will always fail, so you're not seeing any 
files.

import os.path

tokens=['E']
result=[]

for fileName in os.listdir("."):

    if os.path.isfile(fileName) and os.path.splitext(fileName)[1]==".xpm":
        filedata = open(fileName)
        text=filedata.readlines()
        for line in text:
            print line


Once you've tested that, then you're ready to just look at line 24.

text is a list, so you can refer to line 24 as text[24]

Or you can get lines 24-28, with  text[24, 29]   (look up slices in the 
Python doc)
