How do I make combinations between the values in lists in python?

Question

I have 3 lists:

list1=[1,2,3]
list2=[5,6]
list3=[7,8,9]

I want to create following output:

   all_combinations=[[1,5,7],
[1,5,8],
[1,5,9],
[1,6,7],
[1,6,8],
[1,6,9],
[2,5,7],
[2,5,8],
[2,5,9],
[2,6,7],
[2,6,8],
[2,6,9],
[3,5,7],
[3,5,8],
[3,5,9],
[3,6,7],
[3,6,8],
[3,6,9]]

I tried the functions of the itertools library But none of them bring a correct result: itertools.permutations, itertools.combinations

What happened to the 0 in `list3`? – mkrieger1 Apr 22 '21 at 08:52 — mkrieger1, Apr 22 '21 at 08:52
Have you also tried to use `itertools.product`? – mkrieger1 Apr 22 '21 at 08:53 — mkrieger1, Apr 22 '21 at 08:53
The 0 in mistake there I will delete it, – Chana Apr 22 '21 at 08:55 — Chana, Apr 22 '21 at 08:55
No, thanks I'll look at this function – Chana Apr 22 '21 at 08:56 — Chana, Apr 22 '21 at 08:56
tnx mkrieger1, Alex G It works exactly the way I wanted :) – Chana Apr 22 '21 at 09:00 — Chana, Apr 22 '21 at 09:00

Try in this way using itertools

list1=[1,2,3]
list2=[5,6]
list3=[7,8,9,0]
from itertools import product
combs = product(list1,list2,list3)
for i in combs:
    print(list(i))

you don't need `list` in `list(combs)` – Mustafa Aydın Apr 22 '21 at 09:28
