The following will allow you to search a line of text for one of a list
of words.
import re
line = "line of text"
mylist = ["bogus", "text", "here"]
p = re.compile(r"\b(%s)\b" % '|'.join(mylist))
m = p.search(line)
if m: print "Found %s" % m.group(1)
Alternatively, the following will give a list of all words in a string
that appear in the list:
words_found = [word for word in re.split(r"\W+", line) if word in
mylist]

yes this is great i will work from that but how can i use say a list
to pass 10 words?
mylist = ['word1','word2','word3','word4']

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()
