Table of Contents


Python List reverse is a built-in function that reverses the order of elements in a list. It rearranges the items in the list so that the last element becomes the first, the second-to-last becomes the second, and so on.

By using this function, you can easily change the order of elements in a list without having to write complex code. Python List reverse is a useful tool for manipulating lists and can be beneficial in various programming tasks.

In this tutorial, we will discuss the different ways to reverse a list in Python. We will also address a few FAQs on Python List Reverse.

Advantages of Python List reverse()

  1. Easy list reversal: Python List reverse allows you to effortlessly reverse the order of elements in a list.
  2. Simplified code: It provides a simple and concise way to reverse a list without writing complex algorithms.
  3. In-place modification: The reverse() function modifies the original list directly, saving memory and improving efficiency.
  4. Versatile application: Reverse is versatile and applicable to various scenarios, such as sorting, data analysis, and list manipulation.
  5. Time-saving: With Python List reverse, you can quickly achieve list reversal, saving time and effort in your programming tasks.

reverse() method

reverse() is a list data type method that reverses the elements of the list in-place. Rather than creating a new list, this method modifies the existing one.

The reverse() method has the following syntax:


reverse() doesn’t accept arguments.

Here is an example:

capitals = ['Oslo', 'Skopje', 'Riga', 'Madrid']


print('Reversed list:', capitals)

Reversed list: ['Madrid', 'Riga', 'Skopje', 'Oslo']

reversed() function

The Python built-in function reversed() returns a reversed iterator of a given iterable object. The original list has not been altered.

If you only want to iterate over the list's elements in reverse order, use reversed() instead of reversing the elements in place.

The reversed() function has the following syntax:


Where seq is the list you want to revert.

Here's an example of how to use reversed() to loop through the elements of a list in reverse order:

numbers = [1, 2, 3, 4]

for i in reversed(numbers) :


Use the list() constructor, if you want to convert the reversed iterator into a list:

numbers = [1, 2, 3, 4]


[4, 3, 2, 1]

Reverse a List using Slicing

Slice notation is a built-in Python feature that allows you to extract portions of a sequential data type. Although not very Pythonic, the [::-1] notation can be used to reverse a list:

numbers = [1, 2, 3, 4]


Slicing a list produces a new list containing the extracted elements. The original list has not been altered.


[4, 3, 2, 1]

FAQs About Python List reverse()

How does reverse() function work?

The reverse() function modifies the original list in place, rearranging the elements so that the last becomes the first, the second-to-last becomes the second, and so on.

Does the reverse() function return a new list?

No, the reverse() function modifies the original list itself and does not create a new list.

What is the syntax for using reverse() function?

The syntax is: list.reverse()

Can reverse() function be applied to other data types?

No, the reverse() function is specifically designed for Python lists and cannot be used with other data types.

Does reverse() function sort the list as well?

No, reverse() only reverses the order of elements. If you want to sort the list, you need to use a separate sorting function.

Is reverse() function case-sensitive?

No, the reverse() function treats elements in a list as they are without considering case sensitivity.

Can I reverse a portion of a list using reverse() function?

No, reverse() function reverses the entire list. If you want to reverse a portion, you can use slicing and then apply reverse() on the sliced portion.


Use the reverse() method to reverse a Python list in place. Use the reversed() function if you only need to create a reversed iterator.
