Assuming it's primarily the directory walk you need help with,
something like the following should help:

for root, dirs, files in os.walk('~/mydir'):
    for file in [f for f in files if f.endswith(".txt")]:
        fh = open(file)
        for line in fh:
            # Search for words.
        fh.close()
