Is there a better algorithm?

[alex goretoy]

I personally like this solution the best. Thanks mr.

tuples = [(1, 2), (3, 4, 5), (6, 7)]

def triple_or_pair(seq):
   u = None
   try:
       k, u, v = seq
   except ValueError:
       k, v = seq
   return k, u, v

for k, u, v in [ triple_or_pair(seq) for seq in tuples ]:
   print k, u, v
