Oct 22, 2021 · Python comes with a number of methods and functions that allow you to reverse a list, either directly or by iterating over the list object. You’ll learn how to reverse a Python list by using the reversed() function, the .reverse() method, list indexing, for loops, list comprehensions, and the slice method.
Feb 20, 2024 · In Python, we can reverse a list using the negative integer as the Index Jump argument, leaving the Initial and end blank. We must choose the Initial and End values according to a reversed list if the Index Jump value is negative. In this code first, we employ [::-1] to reverse the original list, producing a reversed copy. Python3.
In this tutorial, we will learn about the Python List reverse() method with the help of examples.
In this section, you’ll learn how to reverse Python lists using loops, recursion, and comprehensions. The idea is to get a list and create a copy of it in reverse order. Using a Loop. The first technique you’ll use to reverse a list involves a for loop and a list concatenation using the plus symbol (+):
Oct 15, 2010 · Best solution is using slices with a -1 step size: object[::-1] From a speed perspective, it is best to use the above built-in functions to reverse a list. For reversing, they are 2 to 8 times faster on short lists (10 items), and up to ~300+ times faster on long lists compared to a manually-created loop or generator.
Sep 6, 2022 · The .reverse() method in Python is a built-in method that reverses the list in place. Reversing the list in place means that the method modifies and changes the original list. It doesn't create a new list which is a copy of the original but with the list items in reverse order.

1. Reverse the given list in Python. In the following program, we take a list my_list with values [2, 4, 6, 8, 10]. We have to reverse this list. Call reverse () method on the list my_list. Python Program. my_list = [2, 4, 6, 8, 10] . my_list.reverse() print(my_list) Run Code Copy. Output. [10, 8, 6, 4, 2]
