Python中具有两个列表的元素级concat

Question

我有两个列表：

a = [['Apple'], ['Banana']]
b = [[1,2,3,4], [4,5,6]]

如何将字符串按元素方式连接起来，并获得一个新的列表，如下所示：

new_list = [['Apple1', 'Apple2', 'Apple3', 'Apple4'], ['Banana4', 'Banana5', 'Banana6']]

致以最良好的祝愿

Answer 1

这个能帮你吗

a = [['Apple'], ['Banana']]
b = [[1,2,3,4], [4,5,6]]
print([
    [c + str(d) for d in j for c in i] for i, j in zip(a, b)
])

Output:

[['Apple1', 'Apple2', 'Apple3', 'Apple4'], ['Banana4', 'Banana5', 'Banana6']]
