As can be seen from the above ： In the list 、 Tuples 、 Dictionaries 、 aggregate 、 Array preceded by *, The printed output shows that , The elements in these data structures are divided into independent elements one by one .
Reprinted from ：python In the list 、 Elements 、 Dictionaries 、 The collection and numpy Add an asterisk to the array of * What does it mean , as well as *args and **kwargs Use
