For large source lists the following should be quite fast... months = "jan feb mar apr may jun jul aug sep oct dec".split() lookup = dict(("%02d-%02d" % (mi+1, d), "%02d-%s" % (d, m)) for mi, m in enumerate(months) for d in range(1, 32)) source = ["2008-09-26", "2008-09-28", "2008-09-29"] print [lookup[d[-5:]] for d in source] ... but it is also very brittle. Various compromises are possible, but to find the best would require that you tell us a bit more about your use case. In my experience people are a bit too fast to demand "fast".
