On the other hand, if you want to use an external library on the line 80, you need to import it at the top.

I once asked it for a short example code of something, no longer than 15 lines and it said "here's a code that's 12 lines long" and then added the code. Did it have the specific code "in mind" already? Or was it just a reasonably-sounding length and it then just came up with code that matched that self-imposed constraint?

The latter option is closest, but neither is quite right. It would have ~known~ that the problem asked, combined with a phrase for a 15 line limit has associations with a length of 12 lines (perhaps most strongly 12, but depending on temp it could have given other answers). From there it is constrained to (complete) solutions that lead to 12 lines, from the several (partial) solutions that already exist in the weights.
