list-comprehension

I have a function to pick out lumps from a list of strings and return them as another list:

def filterPick(lines,regex):
    result = []
    for l in lines:
        match = re.search(regex,l)
        if match:
            result += [match.group(1)]
    return result

Is there a way to reformulate this as a list comprehension? Obviously it's fairly clear as is; just curious.
