It's not quite clear to me what the OP's intentions are in the general
case, but calling supersum(item, start) seems odd - for example, is the
following desirable?
>>> supersum([[1], [2], [3]], 4)

I would have thought that the "correct" answer would be 10. How about
the following?
def supersum(sequence, start = 0):
result = start
for item in reversed(sequence):
try:
result = supersum(item, result)
except:
result = item + result
return result
Sorry, I've no idea what I was thinking with that reversed thing. The
following seems better:
def supersum(sequence, start = 0):
result = start
for item in sequence:
try:
result = supersum(item, result)
except:
result = result + item
return result
