Sep 25, 2024 · Given a list, write a Python program to swap the first and last element of the list using Python. Examples: The last element of the list can be referred to as a list [-1]. Therefore, we can simply swap list [0] with list [-1].

You can use "*" operator. my_list = [1,2,3,4,5,6,7,8,9] a, *middle, b = my_list my_new_list = [b, *middle, a] my_list [1, 2, 3, 4, 5, 6, 7, 8, 9] my_new_list [9, 2, 3, 4, 5, 6, 7, 8, 1] Read here for more information.

Apr 6, 2021 · Given a Python list, you have to write a Python program to interchange first and last elements of the list. Consider the below example with sample input and output: We will simply need to swap elements at the first index with the element at the last index in the list. Python provides multiple ways to perform the task. Let's see them, 1.

In this tutorial, we will learn how to interchange or swap first and last element of a list in python. This problem can be solved using basic techniques. This task asks you to interchange two elements of a list. Like array, each element of a list has …

Jan 16, 2023 · def changeList(k): first = k.pop(0) last = k.pop(-1) k.insert(0, last) k.insert(-1, first) return k k = [9, 0, 4, 5, 6] print(changeList(k)) My goal is to interchange the first and last elements in my list. But when I run the code, it switches to this list [6, 0, 4, 9, 5], instead of [6, 0, 4, 5, 9].

Learn how to interchange the first and last elements in a list using a Python program with step-by-step instructions and examples.

Mar 11, 2024 · Python’s * (asterisk) operator allows the unpacking of a list into individual elements, which can be advantageously combined to rearrange elements. This method uses the operator with assignment to switch the first and last elements. Here’s an example: Output: The code defines a function swap_list() that performs unpacking via the asterisk operator.

Jun 30, 2021 · In this tutorial, you will learn how to interchange the first and the last elements in a list in Python. Lists in Python are a group of ordered values that are closed within a square [] bracket.

1. Take the number of elements in the list and store it in a variable. 2. Accept the values into the list using a for loop and insert them into the list. 3. Using a temporary variable, switch the first and last element in the list. 4. Print the newly formed list. 5. Exit.

To swap elements means to interchange their positions within the list. Specifically, swapping the first and last element means the first element becomes the last, and the last element becomes the first. 2. Program Steps. 1. Define a list of elements. 2. Use indexing to swap the first and last elements in the list. 3. Output the modified list. 3.
