I have a list A=[[1,2],[2,3],[4,5]] and i want to insert [2,2] at index=1 in list A. What should i do? I am not suppose to use any package for this. The final array will be: A=[[1,2],[2,2],[2,3],[4,5]] The following code I used but it is giving error:
A.insert([2,2],1)
you can use:
A.insert(1, [2, 2])
from the docs:
list.insert(i, x)
Insert an item at a given position. The first argument is the index of the element before which to insert, so a.insert(0, x) inserts at the front of the list, and a.insert(len(a), x) is equivalent to a.append(x).
