Exception at the end of iterating through a marc file.

When I am Iterating through a marc file containing multiple MARC records, After the last record the following exception is raised.
Traceback (most recent call last):
File "compare_marcs.py", line 320, in
pprint(compare_marc_files(exp, obs))
File "compare_marcs.py", line 299, in compare_marc_files

It sounds like your file might be cut off before the end of the last record, or at least pymarc thinks so. How are you opening the file and creating the reader?

Hi I am opening the files using 'with' .
exp and obs are the two marc files.

with open(exp) as exp_marcs, open(obs) as obs_marcs:
for exp_marc, obs_marc in izip(expected, observed):
do stuff

Thanks,
Shinto.

That's an interesting way to do it. And by interesting I mean I have no idea what it does :-) Can you explain what's going on there?
