It would be easier to process if, when adding a single tuple
to the dict, you could wrap it inside a tuple: (mytup,)
If your data set is not very large and you don't mind the
slight performance hit, you can simplify processing step:
for k,v in col.iteritems():
if not isinstance(v[0], tuple):
v = (v,)
for tup in v: ...
