If there is a big change, it may not, but according to our teacher (the teacher in charge of graduation thesis and defense), the content of electronic papers downloaded or searched online is easy to be found out by experienced teachers, and the defense teacher will ask, since your defense has passed, I don't think you need to worry too much, because the sampling or saving of what is basically not so strict now, and we are often scared by teachers. In fact, it is not that serious, so don't worry too much. Get your other things ready. The defense has passed. If you are really worried, you can take some time to familiarize yourself with the code content and master it. At least you can understand it.
