Hi Aditya,
Add method is used to insert the element and Set method is used to update the Values .
- [adinserter block='9']

Hi Aditya,
add() method adds your specified element to the list at the specified index, the element which previously existed at that particular index and all the following elements will shift 1 index , and the previous element still exists.
Whereas in set() method the element is replaced by the element we want to insert at that particular index.
ex:-
a list – [1,2,3,4,5,6]
on add(0, 9)
the list will be [9,1,2,3,4,5,6]
on set(0,9)
the list will be
[9,2,3,4,5,6]
hope it helps.
