Using the remove() Method: Deleting Specific Elements from Lists

The remove() method deletes the first occurrence of a specific value in the list. This is particularly useful when you know the element's value but not its index.

The syntax of remove() method is:

python

Now, you decide to remove "Kyoto" from your list because you've already visited it. Here's how you can do it:


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

# Remove a specific city
travel_wishlist.remove("Kyoto")
print(travel_wishlist)  # Output: ['Paris', 'Oslo', 'Sydney']

If "Kyoto" isn't on the list, this code will raise an error.


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

# Remove a specific city
travel_wishlist.remove("Kyoto")
print(travel_wishlist)  # ValueError: list.remove(x): x not in list

To avoid this, you can check if the city exists before removing it:


              123456
            
travel_wishlist = ["Paris", "Oslo", "Rome", "Sydney"]

if "Kyoto" in travel_wishlist:
    travel_wishlist.remove("Kyoto")

print(travel_wishlist)

Note

With the remove() method, you can only take out one item at a time.
