I'd just like to mention one more python nicety: list comprehension.
If you wanted the filenames as a list of strings, with each made
lowercase then the following would serve well:
import os
filenames = os.listdir('.')
filenames_lower = [fn.lower() for fn in filenames]
You could also combine this into one line:
import os
filenames_lower = [fn.lower() for fn in os.listdir('.')]
