How to initialize an empty list in Python

In this tutorial, we are going to learn about how to intialize or create an empty list in Python with the help of examples.

Empty list means list doesn’t contain any values in it, so the length of empty list is 0.

Using square brackets []

To initialize a empty list, we can use the square brackets [] syntax in Python.

Here is an example of empty users list:

users = []

We already know Empty lists have length 0, so to find it we can use the len() method in Python.

length = len(users)

print(length) # 0

Using list() constructor

Alternatively, we can also use the list() constructor in Python to initialize an empty list.

Here is an example:

users = list()

To add a items to the empty list , we can use the append() method in Python.

users.append("Olive")

This above line adds Olive to the “users” list.
