How is it possible that I don't get an error message when the range is wrong in list slicing?

Question

today I was learning about list slicing in python, and I have a question about the rules by which python "operates/slices" these lists. How is it possible that I don't get an error message when clearly the range is wrong?

li=[1,2,3,4,5,6]

li[1:12:1]
  [2,3,4,5,6]

Specifying limits out of range simply trims to the end. That is how it works. — zvone, Oct 22 '20 at 22:40
Yeah, it's just the defined semantics. See [here](https://docs.python.org/3/tutorial/introduction.html#strings). — erip, Oct 22 '20 at 22:41
Read the documentation. It's a lot faster than asking StackOverlow. — Frank Yellin, Oct 22 '20 at 22:41
Thank you, but what confuses me is :step, how python runs "steps" after int. 6 in this example? — Aleksandar Savanovic, Oct 22 '20 at 23:03

there isnt an index error it just stops at the end:

li=[1,2,3,4,5,6]

print(li[:10])
print(li[:7])

[1, 2, 3, 4, 5, 6]
[1, 2, 3, 4, 5, 6]

Thank you, I know that, but what confuses me is :step, how python runs "steps" after 6 in this example ? – Aleksandar Savanovic Oct 22 '20 at 22:46
i dont know how they algorithmically do it, you would have to check docs/source code for that – Ironkey Oct 22 '20 at 22:48
