I have an array called numbers.
numbers = [1,2,3,...,8,9,10]
But In the middle of the array, I want to insert section of value, for example: a,b,c
where a,b,c
are under list no 5
.
numbers = [1,2,3,4,5,a,b,c,6,7,...]
Actually, I want to make a multilevel list
1
2
3
4
5
a
b
c
6
7
8
9
10
Any idea or help will really be appreciated
