python合并两个array的问题？

请问如何把两个array的数值合并到一起，比如说array1 = [1,2,3,4,5,6,7,8,9], array[2] = [1,2,3,4,5],我想把它们变成[[1,1],[1,2][1,3],[1,4],[1,5],[2,1],[2,2],[2,3].......[9,1],[9,2],[9,3],[9,4],[9.5]]的一个array，请问怎么做，谢谢

Answer 1

a = [1, 2, 3, 4, 5, 6, 7, 8, 9]
b = [1, 2, 3, 4, 5]
result = [[x, y] for x in a for y in b]
print(result)

Answer 2

a = [1, 2, 3, 4, 5, 6, 7, 8, 9]
b = [1, 2, 3, 4, 5]
result = [[x, y] for x in a for y in b]
print(result)
