I'm finding it a little hard to grok your question / concern.

One does not use os.listdir() to read files. One opens them then uses 
read or readline.

There are many ways to get and filter directory contents.

I guess you would benefit from the glob module.

import glob
fileList = glob.glob('*.txt')
