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]
