grass.script.mlist() provides an interface to g.mlist, although it
only supports glob patterns and not regexps. If you need regexps:

def mlist(type, pattern = None, mapset = None):
    result = list()
    for line in read_command("g.mlist",
                             flags = 'r',
                             type = type,
                             pattern = pattern,
                             mapset = mapset).splitlines():
        result.append(line.strip())
    return result
