But here's the code posted by the OP:
--- Python ---
def pairwise_sum(list1, list2):
result = []
for i in range(len(list1)):
result.append(list1[i] + list2[i])
return result

The code I posted uses one builtin function (zip), the code posted by
the OP uses two (range and len). Neither uses the standard library.
