Convert Range to List in Python (3 Examples)

Hi! This tutorial will show you how to turn ranges to lists in the Python programming language.

Here is an overview:

Let’s dive into the Python code!

Create Example Range of Integers

Here, we will use the range() function to create the example range of integer values that will be transformed into a list in this tutorial.

So, in your Python programming IDE, run the line of code below to create the example range of integer values:

my_range = range(1,10)
 
print(my_range)
 
# range(1, 10)
 
print(type(my_range))
 
# <class 'range'>

With the example range created, let us now see 3 ways it can be turned into a list.
 

Example 1: Turn Range to List Using list() Function

In this first example, we will transform the range object to a list object using the list() function:

my_list = list(my_range)
 
print(my_list)
 
# [1, 2, 3, 4, 5, 6, 7, 8, 9]
 
print(type(my_list))
 
# <class 'list'>

In the above example, we created a range object using the range() function and then parsed that range object as an argument to the list() function.

The list() function takes an iterable as input and returns a list containing the elements of that iterable. In this case, the range object is the iterable, and we get a list containing the same elements as the original range object.
 

Example 2: Turn Range to List Using Splat Unpack Operator

In this next example, we will use Python’s splat unpack operator to change the range to a list:

my_list = [*my_range]
 
print(my_list)
 
# [1, 2, 3, 4, 5, 6, 7, 8, 9]
 
print(type(my_list))
 
# <class 'list'>

Here, we use the splat operator * to unpack the range object and parse its elements as individual arguments to a new list. The splat operator is used to unpack any iterable into individual elements.

In this case, we use the splat operator to unpack the range object into a new list containing the same elements as the original range object.
 

Example 3: Turn Range to List Using List Comprehension

In this final example, we will use list comprehension to convert the range to a list:

my_list = [i for i in my_range]
 
print(my_list)
 
# [1, 2, 3, 4, 5, 6, 7, 8, 9]
 
print(type(my_list))
 
# <class 'list'>

In the above example, we used list comprehension to turn the range object into a list. List comprehension is a concise way to create a list in Python, and it works by iterating over an iterable and applying a transformation to each element.

In this case, we iterate over the range object using for i in my_range, and then add each element to a new list using the syntax [i for i in my_range]. The resulting list will contain the same elements as the original range object.

So, with that, we have demonstrated, with 3 simple examples, how to convert a range to a list in Python. I hope you found this tutorial helpful!
