Yes, but the question is "what is *it* that is stored? The answer is, it isn't a list, despite the name you choose. It is an enumerate iterator object, and iterator objects can only be iterated over once. If you really, truly need a list, call the list constructor: aList = list(enumerate(numList)) but that's generally a strange thing to do. It is more common to just call enumerate when you need it, not to hold on to the reference for later. -- Steven D'Aprano "Ever since I learned about confirmation bias, I've been seeing it everywhere." -- Jon Ronson -- https://mail.python.org/mailman/listinfo/python-list
