The list.insert() method in Python allows you to add an element at a specific position in a list. Instead of replacing any items, it shifts the existing elements to make room for the new one.
Key Points:
Insert at a Specific Position: You can add an element at any position in the list by specifying where it should go.
Insert at the Beginning: To add an element at the start, you specify the first position.
Insert at the End: If the position you specify is beyond the list’s length, the element is added at the end.
Insert Using Negative Positioning: Negative positions allow you to insert elements relative to the end of the list.
Examples of Usage:
Adding a number in the middle of a list.
Adding an element at the start or end.
Using negative positioning to place an element before the last few items.
This method directly updates the list and is helpful when you need precise control over where elements are added.
