Answer 1

list[a:a] = ... can be used to insert an iterables inside lists.

String is an iterable, it is a collection of characters, thus s[1:1] = "b" is possible.

But integer is not an iterable and thus n[1:1] = 1 results in error, but you can do n[1:1] = [1]

Answer 2

The reason why s is affected because "b" is a str object, which is an iterable. Int objects are not iterables, you cannot assign them to a list.
Change the int value to an iterable like a string, it will works.
n[1:1]='a'

Answer 3

Thanks for the answers. I got it.
