execute similar files in different directories python
<p>I about 100 files each stored in a different directory. I have written a script but currently I am running this script for all of these files one at a time. I know if I save these files in one directory I can run them all one after the other using os.chdir, os.listdir. 
But for me moving them to one directory is not an option.
Is there a way to execute all these files consecutively in a order and make my life easier? </p>
