Deleting Elements

The del keyword allows you to delete an element at a specific index in the list. This is useful when you know the exact position of the item you want to remove.

The syntax of del keyword is:

The statement starts with the keyword del;
Next, you typically identify the list item with its index, like list[index].

Let's say you have a list of cities in your travel itinerary:

You've decided to remove the city "Sydney", which is the last destination on your list. Using del and negative indexing:


              12345
            
travel_wishlist = ["Paris", "Oslo", "Kyoto", "Sydney"]

# Remove the last city
del travel_wishlist[-1]
print(travel_wishlist) # Output: ['Paris', 'Oslo', 'Kyoto']

Now, the list is down to three cities:

You can remove any item from the list by using its index number.
