Swap Elements in list of PythonSo far, we have performed a variety of operations on lists in Python. In this article, we will learn how we can swap the elements of a list. But first, let's understand what swapping is all about? Swapping is a process in which two variables exchange the values that they hold. For example, If a variable A holds an integer value of 10 and a variable B holds an integer value of 20, then on swapping B will hold 20 and A will hold 10. We will use the following approaches to swap the elements in the list.
So, let's get started with the first one, The Basic SwapHere, we will the basic idea of swapping to swap the elements of list. The following program illustrates the same, Output: The values inside the list are: [20, 13, 41, 11, 10, 29] The list with swapped elements is: [20, 10, 41, 11, 13, 29] Explanation- It's time to understand what we have done in the above program,
In the second program, we shall see how pop() can be used here. Using pop() functionConsider the program given below, Output: The values inside the list are: [20, 13, 41, 11, 10, 29] The list with swapped elements is: [20, 10, 41, 11, 13, 29] Explanation- It's time to have a glance at the explanation of the above program,
Finally, we shall see how a tuple variable can be used to swap the elements of a list in Python. Using a Tuple VariableThe program given below shows how it can be done, Output: The values inside the list are: [20, 13, 41, 11, 10, 29] The list with swapped elements is: [20, 10, 41, 11, 13, 29] Explanation- Let's see what happened here,
ConclusionIn this tutorial, we learned what swapping is and how it can be implemented among the elements of a list present in Python.
