Python Initialize List: 4 Easy Ways to Learn

In this tutorial, we will discover the four easy ways to learn Python Initialize List. But first, let’s know what is python list.

A Python List is simply a sequence of numbers or other values. This means that the list’s values can cover a wide range of possibilities. The list itself is a container whose contents can be altered. That means we can modify the current values by adding new ones or removing old ones.

Furthermore, a finite sequence is represented by the python list. Elements or items are the values contained in a list. A Python list, on the other hand, can have the same value many times, unlike set.

How to Declare a List in Python?

The popular method of declaring a list in python is using square brackets []. Lists store zero or more elements. An item is a component of each list, whereas Python lists are often referred to as arrays.

In Python, list elements are separated by commas, while the list itself is enclosed in a set of square brackets.

Here’s an example of a list in Python:

website= [‘Python for Free’, ‘Proud Pinoy’, ‘IT Sourcecode’]

Our list contains three values: Python for Free, Proud Pinoy, and IT Sourcecode. We can reference our list by using the variable “website” that we declared above.

How to Create a List in Python?

We can create a list in Python using square brackets, the list() method, list multiplication, and list comprehension.

We can initialize an empty list or a list with default values using square brackets. The list() method functions are similar to square brackets. If you want to add starting values, you must add square brackets and a list of items within the list() method.

Meanwhile, List multiplication enables the creation of a new list consisting of repeated components from an existing list. While List comprehensions allow you to generate a new list from an existing list’s elements.

Python Square Brackets Create List

This time, we will focus on how to use the square brackets approach to create a list. To create a list with empty values in python, we can use square brackets or list() method.

Here’s an example syntax:

python= []

We use the print() method to return blank square brackets with no value inside that represent a blank list.


Example Program with default values:

jobs = ['Software Engineer','Data Analyst']

Python Create List() Method

Using the list() method is another method to create an empty list with no values in Python.

Here is the list() function that creates a list with no values:

jobs = list()



The results of the first two methods are the same: an empty list. Neither of these methods has been standardized for usage under any given conditions. As a general rule, the method of using empty square brackets ([]) is preferred due to its concision.

Python Declare List Multiplication

List multiplication is one way to initialize a list with multiple values. Using this method, you can generate a set of parameters with a fixed number of possible values.


favorite_books = [''] * 10


['', '', '', '', '', '', '', '', '', '']

Python Declare List Comprehension

The list comprehension method can also be used to create an empty list with default values. The term “list comprehension” in Python is used to describe a method for generating lists from an already-existing iterable object.

In addition, it is a useful way to define a list based on an iterator because it is elegant, simple, and widely recognized.

The iterable object can be anything that can be traversed in a for loop, such as a list or the result of a range() command.


favorite_fruits = ['Choose a fruit.' for i in range(10)]


['Choose a fruit.', 'Choose a fruit.', 'Choose a fruit.', 'Choose a fruit.', 'Choose a fruit.', 'Choose a fruit.', 'Choose a fruit.', 'Choose a fruit.', 'Choose a fruit.', 'Choose a fruit.']


In summary, Python Initialize List is a cornerstone of any list-based operation. This guide shows us how to use square brackets [] and the list() method to create empty lists and with data. Furthermore, we discussed methods for producing lists with a fixed number of values, such as list multiplication and list comprehension.
