() do? In fact, the map () function is the mapping relationship of a dataset to another dataset, and the middle does not decrease or add elements. So in Python, the map () function simply takes the elements of multiple list objects out of order, and then puts them into the function to manipulate them and calculate the results. It is a parallel relationship and does not reduce the element. As in the following exam
