#*y stands for tuple, **z stands for dictionary. The * sign in front of *[1,2,3,4,5] means that each element in the list is taken out and assigned, if there is no * sign, the list is assigned as a whole
#The result is [11,22,33,44,55] and none because the function func(li) does not get a return value, it does not get the result, so it is none
#The result is 210 because there are two functions in this question that are both func and the same name function, then execute the following anonymous function, so it is 210
