combinations - Python get all permutations of numbers

Question

I'm trying to display all possible permutations of a list of numbers, for example if I have 334 I want to get:

3 3 4
3 4 3
4 3 3

I need to be able to do this for any set of digits up to about 12 digits long.

I'm sure its probably fairly simple using something like itertools.combinations but I can't quite get the syntax right.

TIA Sam

Answer 1

>>> lst = [3, 3, 4]
>>> import itertools
>>> set(itertools.permutations(lst))
{(3, 4, 3), (3, 3, 4), (4, 3, 3)}
