我怎么能得到基于两个指标的东西的价值?

Question

我想在两个列表中找到分数

A=[2,3,5]
B=[6,7,0]

让分数减去2个数字。我如何定义分数，我可以通过索引I和j得到它的值?

:

score[0][1]=-5        which is 2-7=-5

或

score[1][2]=3         which is 3-0=3

我不知道怎么做!

Answer 1

双列表推导式很容易解决这个问题

A = [2, 3, 5]
B = [6, 7, 0]
score = [[i - j for j in B] for i in A]
print(score[0][1])  # -5
print(score[1][2])  # 3

整个score数组

[[-4 -5  2]
[-3 -4  3]
[-1 -2  5]]
