Here is a ready to use way of doing this, based on the other answers. It's not the most performance critical, but it works as described;

def reglob(path, exp, invert=False):
    """glob.glob() style searching which uses regex

    :param exp: Regex expression for filename
    :param invert: Invert match to non matching files
    """

    m = re.compile(exp)

    if invert is False:
        res = [f for f in os.listdir(path) if m.search(f)]
    else:
        res = [f for f in os.listdir(path) if not m.search(f)]

    res = map(lambda x: "%s/%s" % ( path, x, ), res)
    return res
