python如下函数返回两个数的平方和_计算Lis中数字平方和的函数

我试着写一个平方和(xs)函数来计算列表xs中数字的平方和。例如，平方和([2，3，4])应返回4+9+16，即29：

我试过的是：import random

xs = []

#create three random numbers between 0 and 50

for i in range(3):

xs.append(random.randint(0,50))

def sum_of_squares(xs):

#square the numbers in the list

squared = i ** i

#add together the squared numbers

sum_of_squares = squared + squared + squared

return sum_of_squares

print (sum_of_squares(xs))

现在这个总是印出来的12

因为它把i作为列表中整数的数量，而不是整数的值。我该怎么说“将值乘以整数的值”，因为列表中有很多整数可以得到平方值？

问这个问题让我试着说：import random

xs = []

#create three random numbers between 0 and 50

for i in range(3):

xs.append(random.randint(0,50))

def sum_of_squares(xs):

#square the numbers in the list

for i in (xs):

squared = i ** i

#add together the squared numbers

sum_of_squares = squared + squared + squared

return sum_of_squares

print (sum_of_squares(xs))

但它似乎没有正确地对正整数的值-我不确定它在做什么。请参见本屏幕截图中的Visualize Python演练。
