While making an app I tried to think in a way to collect all the possible orders and combinations of an unknown length list in python. As an example, I have a list

[1, 2]

I want a way to make as an example list like this

[[1, 1, 1], [1, 1, 2], [1, 2, 1], [1, 2, 2], [2, 1, 1], [2, 1, 2], [2, 2, 1] [2, 2, 2]]

Yes I want a a bigger combination of list with all possible order and all with the same length as the example above

I was trying to find a way to do that but almost all of my ways ends in time run error So it would be helpful if anyone could help me and thanks

`almost all of my ways ends in time run error ` ..Can u pls attach the code that you getting errors? – Bhargav - Retarded Skills Dec 22 '22 at 20:13
probably with `itertools.product` – Jean-François Fabre Dec 22 '22 at 20:13
Is it possible by itertools.product to have a bigger lists – شريف Player Dec 22 '22 at 20:15

for instance : `list(itertools.product([1, 2],repeat=3))` – Jean-François Fabre Dec 22 '22 at 20:15
Or `list(itertools.product(*[smalllist]*n)` where smalllist is your starting list, and n the length of your 'combinations', – Swifty Dec 22 '22 at 20:17

@Jean-FrançoisFabre I fixed the duplicate closure; the other question is only tangentially related. – Karl Knechtel Feb 28 '23 at 22:03
