我有一个元组列表,想通过组合各个元组元素来获取它们的乘积。
例如:
lists = [
[(1,), (2,), (3,)],
[(4,), (5,), (6,)]
]
p = itertools.product(*lists)
for product in p:
print product
这会导致一堆元组的元组:
((1,), (4,))
((1,), (5,))
((1,), (6,))
((2,), (4,))
((2,), (5,))
((2,), (6,))
((3,), (4,))
((3,), (5,))
((3,), (6,))
我想要的是像这样的元组列表:
(1,4)
(1,5)
(1,6)
(2,4)
(2,5)
(2,6)
(3,4)
(3,5)
(3,6)
我也希望您能将其应用于任何数量的元组列表。
因此,在三个元组的情况下:
lists = [
[(1,), (2,), (3,)],
[(4,), (5,), (6,)],
[(7,), (8,), (9,)]
]
p = itertools.product(*lists)
for product in p:
print product
I'd like:
(1, 4, 7)
(1, 4, 8)
(1, 4, 9)
(1, 5, 7)
(1, 5, 8)
(1, 5, 9)
(1, 6, 7)
(1, 6, 8)
(1, 6, 9)
(2, 4, 7)
(2, 4, 8)
(2, 4, 9)
(2, 5, 7)
(2, 5, 8)
(2, 5, 9)
(2, 6, 7)
(2, 6, 8)
(2, 6, 9)
(3, 4, 7)
(3, 4, 8)
(3, 4, 9)
(3, 5, 7)
(3, 5, 8)
(3, 5, 9)
(3, 6, 7)
(3, 6, 8)
(3, 6, 9)
