The insert() method inserts an element to the list at the specified index.
Example
Syntax of List insert()
The syntax of the insert() method is
list.insert(i, elem)
Here, elem is inserted to the list at the ith index. All the elements after elem are shifted to the right.
insert() Parameters
The insert() method takes two parameters:
- index - the index where the element needs to be inserted
- element - this is the element to be inserted in the list
Notes:
- If index is 0, the element is inserted at the beginning of the list.
- If index is 3, the index of the inserted element will be 3 (4th element in the list).
Return Value from insert()
The insert() method doesn't return anything; returns None. It only updates the current list.
