给定一个排序的整数列表，将元素平方并按排序顺序给出输出

Question

Can anybody help me with this. I don't know what am I doing wrong over here

list = [-9, -2, 0, 2, 3]
squared_list=[]


for element in list:
    squaring = list[element] * list[element]
    squared_list.append(squaring)

squared_list.sort()
print(squared_list)

Answer 1

使用squaring = element * element反对squaring = list[element] * list[element]因为对于第一个元素，例如，您正在咨询 list[-9] 并且该索引已出。
