为什么不需要定义一下List
def square_of_sum(L): sum = 0 for x in L: sum = sum + x * x return sum print square_of_sum([1, 2, 3, 4, 5]) print square_of_sum([-5, 0, 5, 15, 25])
def square_of_sum(L): sum = 0 for x in L: sum = sum + x * x return sum print square_of_sum([1, 2, 3, 4, 5]) print square_of_sum([-5, 0, 5, 15, 25])
