Lets assume you have files in the folder path path = /home/username/foldername/

so you have all the files in the path folder, to read all the files in the folder you should use os or `glob' to do that.

import os
path = "/home/username/foldername/"
savepath = "/home/username/newfolder/" 
for dir,subdir,files in os.walk(path):
    infile = open(path+files)
    outfile = open(savepath,'w')
    a = infile.readline().split('.')
    for k in range (0,len(a)):
        print(a[0], file=outfile, end='')
infile.close()
outfile.close
print "done"

or using glob you can do it much lesser lines of code.

import glob
path = "/home/username/foldername/"
savepath = "/home/username/newfolder/"
for files in glob.glob(path +"*.txt"):
    infile = open(files)
    outfile = open(savepath,'w')
    a = infile.readline().split('.')
    for k in range (0,len(a)):
        print(a[0], file=outfile, end='')
infile.close()
outfile.close
print "done" 

hope it might work for you.
