# How to Remove Items in a List in Python Using the del Keyword names = You can also specify a particular item to be removed using its index. The pop() method removes the last item in the list. How to Remove Items in a List in Python Using the pop() Method names = How to Remove Items in a List in Python Using the remove() Method names = Īs you can see in the example above, we passed in the item to be removed as a parameter in the remove() method: names.remove('John'). We can use the following methods to remove an item from a list:

Python add to list code#

In the code above, we changed the value of the first item from 'Jane' to 'Doe' using the item's index: names = 'Doe'. To change the value of an item in a list, you have to make reference to the item's index and then assign a new value to it. Index -4 = Jane How to Change the Value of Items in a Python List Using negative indexing, we can access items starting from the end of the array. The item printed out was 'Jane' because it is the first item in the list. In the example above, we printed the item with index 0: print(names). You can access items in a list using the item's index. Lists are zero-indexed so the first item is 0, the second item is 1, the third item is 2, and so on. In our example, we added 'Doe' at the second index. When adding items to a list using the insert() method, you specify the index where it should be placed. The append() method, seen in the last section, adds an item at the last index of a list. How to Add Items to a List in Python Using the insert() Method In the code above, we added 'Doe' to list using the append() method: names.append('Doe'). The new item to be added will be passed in as a parameter to the append() method. Using dot notation, we can attach the append() method to a list to add an item to the list. How to Add Items to a List in Python Using the append() Method We can use two methods to add items to a list – the append() and insert() method. In the code above, we created a list called names with four items – Jane, John, Jade, and Joe. This will help you understand the syntax in the last section. How to Add Items to a List in Pythonīefore we start adding items to the list, let's create it. In the next section, you'll see how to add items to a list. You can either store a particular data type or mix them. Note that lists can have/store different data types. Here's what a list looks like: ListName = To create a list in Python, we use square brackets ( ). You'll see how to do this in the examples in this article. This means that you can modify the value of an item in a list. They remain in the same order as you create and add items to a list. This means that you can add two or more items with the same name.

Here are some of the features of a list in Python: You'll see some of the features of lists in Python, how to create them, and how to add, access, change, and remove items in a list. Each of them have their own syntax and features. Some of these data structures include Lists, Sets, Tuples, and Dictionaries. You can use some of the inbuilt data structures in Python to organize and store a collection of variables.
