Sure, piece of cake:

#!/usr/bin/env python

import os

def textfiles(path):
    include = ('.txt', '.csv',)
    for root, dirs, files in os.walk(path):
        for name in files:
            prefix, ext = os.path.splitext(name)
            if ext.lower() not in include:
                continue
            filename = os.path.join(root, name)
            yield filename

path = os.getcwd()
for name in textfiles(path):
    print name
