The append() Method

The append() method in Python is used to add an element to the end of a list. It's a convenient way to expand a list dynamically without having to create a new one.

Imagine you have a list of cities you want to visit. You've already listed a few, but as your plans evolve, you want to add more cities without replacing the existing ones.

The list currently contains four cities. Now imagine you want to add another city, say "Sydney". Here's how you can do it:


              123456
            
travel_wishlist = ['Paris', 'Tokyo', 'New York', 'Rome']

# Adding a new city to the travel wishlist
travel_wishlist.append("Sydney")

print(travel_wishlist) # Output: ['Paris', 'Tokyo', 'New York', 'Rome', 'Sydney']

As you can see, "Sydney" has been added to the end of the list without affecting the existing items.

Note

The list grows by one element every time you use append();

You can append not only strings but also variables, numbers, or even other lists;

The same logic applies to integers, floats, or any object.

The append() method allows you to efficiently update your list without recreating it. Additionally, this method is especially practical in for loops, where you can dynamically build or grow a list by adding elements iteratively based on conditions or computations.
