Someone helped me with some code yesterday and I'm trying to

subjects = (info[2] for info in items)
Perhaps I'm not truly understanding what this does. Does this do
anything different than if I wrote
for info[2] in items
subject = info[2]
Close -- the correct form is
for info in items:
subject = info[2]
Basically, python goes through the elements of items, assigning each one
to the name 'info' during that loop; then in the body of the loop, you
can access the attributes/elements/methods/whatever of the info object.
Hope this helps!

Ack. My correction only dealt with the info[2] issue on the for line;
Emille's answer properly matches the original code.
Sorry.
