bookThe insert() Method

What if we want to add an item not at the end of the list, but at a specific position? For this purpose, we use the insert() method.

The syntax for the insert() method is:

  • index: the position in the list where you want to add the new element. Remember, Python uses zero-based indexing;
  • element: the item you want to insert into the list.

Imagine planning a trip and having a list of cities you want to visit.

123
travel_wishlist = ["Paris", "Oslo", "Kyoto", "Sydney"] print(travel_wishlist) # Output: ['Paris', 'Oslo', 'Kyoto', 'Sydney']
copy

This list contains four items:

However, your plans change, and you decide to adjust the order of destinations. Now, you want to prioritize "Chicago" as the first destination.

12345
travel_wishlist = ["Paris", "Oslo", "Kyoto", "Sydney"] # Adding "Rome" as the first destination travel_wishlist.insert(0, "Chicago") print(travel_wishlist) # Output: ['Chicago', 'Paris', 'Oslo', 'Kyoto', 'Sydney']
copy

After this, "Chicago" takes the 0 index. It's now at the top, and the rest of the items have shifted down. So, we now have 5 items:

Note

With the insert() function, you can add only one item at once.

You have the original travel wishlist: ["Paris", "Oslo", "Kyoto", "Sydney"].

You've decided to prioritize two specific cities for your travels using the insert() method.

  • Add the first city as the new first destination in your list;
  • Then, add the second city right after the trip to Paris.
