How to insert an element at a specific position in a list in Python

How to insert an element at a specific position in a list in Python.

Here is a step-by-step tutorial on how to insert an element at a specific position in a list in Python:

1. First, create a list in Python. You can create a list by enclosing elements in square brackets [] and separating them with commas. For example, let's create a list named my_list with some initial elements:

my_list = [1, 2, 3, 4, 5]

2. Next, identify the position at which you want to insert the new element. Remember that in Python, list positions start from 0. So, if you want to insert an element at the first position, it will have an index of 0.

3. Once you have the position, decide on the element you want to insert. For demonstration purposes, let's say we want to insert the number 10 at the third position (index 2) in the my_list.

4. Now, use the insert() method to insert the element at the desired position. The insert() method takes two arguments: the index at which you want to insert the element, and the element itself. In our case, we will use my_list.insert(2, 10) to insert the number 10 at index 2.

my_list.insert(2, 10)

5. After executing the above code, the element 10 will be inserted at the third position (index 2) in the my_list. The updated list will be [1, 2, 10, 3, 4, 5].

6. If you want to insert multiple elements at once, you can pass a list of elements as the second argument to the insert() method. For example, to insert the numbers 6, 7, and 8 at the end of the my_list, you can use my_list.insert(len(my_list), [6, 7, 8]).

my_list.insert(len(my_list), [6, 7, 8])

7. After executing the above code, the elements [6, 7, 8] will be inserted at the end of the my_list. The updated list will be [1, 2, 10, 3, 4, 5, [6, 7, 8]].

That's it! You have successfully inserted an element at a specific position in a list in Python. Remember to adjust the position based on the zero-based indexing of Python lists.
