This sounds better, it's probably faster than the RE version, Python
2.5 has a really fast str.__contains__ method, done by effbot:

def lines_with_words(file, word1, word2):
    """Print all lines in file that have both words in it.
    (word1 may be the less frequent word of the two)."""
    for line in file:
        if word1 in line and word2 in line:
            print line
