my_list = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
I want to start from number: 4
So how can I sort the list like:
sorted_my_list = [4, 5, 6, 7, 8, 9, 10, 1, 2, 3]

That doesn't make sense. The second list is not sorted. – Ken Kinder Jun 08 '20 at 14:14

You could probably use the index() function on the list to find the position of the desired position/number. But I don't know of the side effects.
my_list = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
starter = 4
result = my_list[my_list.index(starter):] + my_list[:my_list.index(starter)]
Is this something to your liking?
And if you need to sort the two section, add sorted() to them, altho I don't see the point of this.
result = sorted(my_list[my_list.index(starter):]) + sorted(my_list[:my_list.index(starter)])
Final edit I think. If you need to sort the list first, and then split on the 4 you would have to sort the entire list/data before hand, to get the split down the list to be correct. Otherwise you'd end up with incorrect orders if the numbers were un-sorted before the split (my_list = [1, 2, 4, 3, 5, 6, 7] for instance)
my_list = sorted([1, 2, 3, 4, 5, 6, 7, 8, 9, 10])
starter = 4
result = my_list[my_list.index(starter):] + my_list[:my_list.index(starter)]

@js-on You sure? I'm gettnig `[4, 5, 6, 7, 8, 9, 10, 1, 2, 3]`. Which seams to match. – Torxed Jun 08 '20 at 14:17

I think this is the correct answer, as to why you want to do something like this... – E.Serra Jun 08 '20 at 14:18

@E.Serra I have **no** idea haha. But thought it was a good mental break from work trying to solve it with as little readable code as possible. – Torxed Jun 08 '20 at 14:20
