While technically correct, I don't think you could claim that it's "just
noise" in this example:
try:
for ORlist in includes:
try:
for filter in ORlist:
for field in curr_fields:
for item in record[field]:
if match(item, filter):
raise Found
else:
raise NotFound
except Found:
continue
except NotFound:
continue
else:
result.append(record)
