假设我有以下内容。
a = [[1,2,3],[4,5,6],[7,8,9]]
b = [['a','b'],['c','d'],['e','f']]
我如何获得以下内容？
[1,2,3,'a','b']
[1,2,3,'c','d']
[1,2,3,'e','f']
[4,5,6,'a','b']
[4,5,6,'c','d']
[4,5,6,'e','f']
[7,8,9,'a','b']
[7,8,9,'c','d']
[7,8,9,'e','f']
最佳答案
from itertools import product
a = [[1,2,3],[4,5,6],[7,8,9]]
b = [['a','b'],['c','d'],['e','f']]
print [x+y for (x,y) in product(a,b)]
