Hello everyone, I am now about halfway through the Python fundamentals course on kaggle. But I'm faced with a problem on the Loops and List Comprehension excercise. I was showing my little brother some of the cool things you could do, but whilst showing him I messed up one of my exercises, I kept looking for a way to reset the notebook to have the original code of the exercise back, but I can't find any way to do this. I decided to continue the rest of the excercises and keep searching after, now that I've completed all the rest there's one excercise left I have to complete to get 100% which is the one where I've lost the code for. I can't find any way to get a reset version of the notebook, can anyone help me out there. Thanks in advance.
