Python List append() Method Example | Python Standard Libary is today’s topic. Python has a great built-in list type named “list.” List literals are written within square brackets [ ]. Lists work similarly to strings, use the len() function and square brackets [ ] to access data, with the first element at index 0. The append() method in Python appends an element or item to the end of the list. The list append() method adds a single element to the existing list. It doesn’t return a new list; instead, it modifies the original list.

Python List append() Method Example

The syntax of append() method is following.

list.append(item)

append() Parameters

The list append() method takes a single element and adds it to the end of the list. An element can be numbers, strings, another list, dictionary, etc.

Adding Element to a List in Python

Let us create a file called app.py and add the following code inside it.

// app.py

GoT = ['Daenerys', 'Jon', 'Tyrion']
Friends = 'Rachel'

GoT.append(Friends)
print(GoT)

Save the file and go to the cmd or terminal and run the file using the following command.

python3 app.py

Now, write the following code inside the app.py file.

GoT = ['Daenerys', 'Jon', 'Tyrion']
Friends = ['Rachel', 'Monica', 'Phoebe']

GoT.append(Friends)
print(GoT)

In the above example, we are adding a list to the list. So the second list considers as a single list item and it appends as a separate item. The output is following.
