yes, the position can matter when using the insert command. for instance, in a list or an array, using the insert command with a specified position will add the new element at that position, shifting existing elements to accommodate it. in databases, the position doesn't typically matter as...
When the user calls the insert method and passes the index, the function first checks its existence in the list. If it exists, then the element gets inserted at the given position in the list. After that, it also updates the indexes of the rest of the items. ...
