Ok, I've seen the zip function before and it might do the job, but here
I think you're suggesting:
for i in range(len(records)-1):
for r1, r2 in zip(records[i], records[i+1]):
if r1.xx == r2.xx
.
.
The hope was to do the loop without subscripts, and this may or may not
have gotchas because records is a namedtuple:
for r in records(1:):
.
.
