2 Methods to Insert Item at Index 0 of List Python

This article focuses on inserting an item at index 0 in a Python list. To insert, we'll use:

1. insert() method
2. + operator method

Insert at index 0 using the insert() method

The insert() function inserts an item in a list at a specified index. We can use this function to insert an item at index 0.

In the following example, we will insert the value "HTML" at index 0 of the my_list list.

my_list = ["Python", "Django", "Javascript"] # 👉️ List

new_list = my_list.insert(0, "HTML") # 👉️ Insert at index 0

print(my_list) # 👉️ Print

Output:

['HTML', 'Python', 'Django', 'Javascript']

As observed, the value "HTML" has been successfully inserted at index 0 of the my_list list.

Insert at index 0 using the + operator

We can also use the + operator to insert at index 0. With the + operator, we can insert one item or more in the front of a list.

The example below will utilize the + operator to insert the value "HTML" at index 0:

my_list = ["Python", "Django", "Javascript"] # 👉️ List

new_list = ["HTML"] + my_list # 👉️ Megre ["HTML"] with my_list

print(new_list) # 👉️ Print

Output:

['HTML', 'Python', 'Django', 'Javascript']

What we did:

1. Converted the string "HTML" into a list using the list brackets [].
2. Merged the two lists using the + operator.

To insert multiple items at index 0 of a list, follow the example below:

my_list = ["Python", "Django", "Javascript"] # 👉️ List

list_to_insert = [1, 2, 3, 4] # 👉️ List to Insert

new_list = list_to_insert + my_list # 👉️ Megre list_to_insert with my_list

print(new_list) # 👉️ Print

Output:

[1, 2, 3, 4, 'Python', 'Django', 'Javascript']

Here, we have inserted multi numbers at the front of my_list. You can visit Append Multiple Items to List in Python for more information about inserting multi items.
