Better question is why is there a try with no except...

Better yet, WHY is there two TRY statements when there could quite
happily be only one...

Towards what you are asking, I GUESS...because the author hoped to
handle the cases where cur failed to get assigned...but then
his .close method of it would likely not work anyway...I mean...does
this even work...YUCK
