Enumerate (iteration, start): Returns an enumerated object. An iterator (iteration) must be another iteration object that can be supported. The initial value defaults to zero, that is, if you do not enter start, that means zero-based. The input to an iterator can be a list, a string, a collection, and so on, because these are the objects of the class iteration. Returns an object, if you are in the form of a list, it is a list, each element of the list
