What does the .insert(index, item) method do?

The .insert(index, item) method is designed to add an item at a specific position within a list. When you call this method, you specify an index, which indicates where in the list you want to insert the new item. The current element at that index and any subsequent elements are shifted one position to the right to accommodate the new item. This allows for precise control over where elements are placed in the list, making it useful for maintaining an ordered collection of items or for modifying lists in a structured way.

This method is particularly important in scenarios where the order of elements is essential, such as when implementing algorithms that require specific arrangements of data. Understanding how this method works can help in managing data more effectively when working with lists in programming.
