dir_name = 'mydirectory'
extension = 'my extension'
import os
files = os.listdir(dir_name)
files_with_ext = [file for file in files if file.endswith(extension)]

That will only do the top level (not subdirectories), but you can use
the os.walk procedure (or some of the other procedures in the os and
os.path modules) to do that.
